commit 054c5145540e5ad5b80adf23a5e3e2fc281fb8aa upstream. usbtmc_read() calls usbtmc_generic_read() which uses interruptible sleep, but usbtmc_read() itself uses uninterruptble sleep for mutual exclusion between threads. That makes no sense. Both should use interruptible sleep.

2025-06-04usb: typec: tcpm: delay SNK_TRY_WAIT_DEBOUNCE to SRC_TRYWAIT transitionRD Babiera1-1/+1
commit e918d3959b5ae0e793b8f815ce62240e10ba03a4 upstream. This patch fixes Type-C Compliance Test TD 4.7.6 - Try.SNK DRP Connect SNKAS. The compliance tester moves into SNK_UNATTACHED during toggling and expects the PUT to apply Rp after tPDDebounce of detection. If the port is in SNK_TRY_WAIT_DEBOUNCE, it will move into SRC_TRYWAIT immediately and apply Rp. This violates TD 4.7.5.V.3, where the tester confirms that the PUT attaches Rp after the transitions to Unattached.SNK for tPDDebounce. Change the tcpm_set_state delay between SNK_TRY_WAIT_DEBOUNCE and SRC_TRYWAIT to tPDDebounce.

2025-06-04usb: uhci-platform: Make the clock really optionalAlexey Charkov1-1/+1
commit a5c7973539b010874a37a0e846e62ac6f00553ba upstream. Device tree bindings state that the clock is optional for UHCI platform controllers, and some existing device trees don't provide those - such as those for VIA/WonderMedia devices. The driver however fails to probe now if no clock is provided, because devm_clk_get returns an error pointer in such case. Switch to devm_clk_get_optional instead, so that it could probe again on those platforms where no clocks are given.

2025-05-02USB: OHCI: Add quirk for LS7A OHCI controller (rev 0x02)Huacai Chen1-0/+23
commit bcb60d438547355b8f9ad48645909139b64d3482 upstream. The OHCI controller (rev 0x02) under LS7A PCI host has a hardware flaw. MMIO register with offset 0x60/0x64 is treated as legacy PS2-compatible keyboard/mouse interface, which confuse the OHCI controller. Since OHCI only use a 4KB BAR resource indeed, the LS7A OHCI controller's 32KB BAR is wrapped around (the second 4KB BAR space is the same as the first 4KB internally). So we can add an 4KB offset (0x1000) to the OHCI registers (from the PCI BAR resource) as a quirk.

2025-05-02usb: cdns3: Fix deadlock when using NCM gadgetRalph Siemsen1-0/+2
commit a1059896f2bfdcebcdc7153c3be2307ea319501f upstream. The cdns3 driver has the same NCM deadlock as fixed in cdnsp by commit 58f2fcb3a845 ("usb: cdnsp: Fix deadlock issue during using NCM gadget"). Under PREEMPT_RT the deadlock can be readily triggered by heavy network traffic, for example using "iperf --bidir" over NCM ethernet link. The deadlock occurs because the threaded interrupt handler gets preempted by a softirq, but both are protected by the same spinlock. Prevent deadlock by disabling softirq during threaded irq handler.

2025-05-02USB: serial: simple: add OWON HDS200 series oscilloscope supportCraig Hesling1-0/+7
commit 4cc01410e1c1dd075df10f750775c81d1cb6672b upstream. Add serial support for OWON HDS200 series oscilloscopes and likely many other pieces of OWON test equipment. OWON HDS200 series devices host two USB endpoints, designed to facilitate bidirectional SCPI. SCPI is a predominately ASCII text protocol for test/measurement equipment. Having a serial/tty interface for these devices lowers the barrier to entry for anyone trying to write programs to communicate with them. The following shows the USB descriptor for the OWON HDS272S running firmware V5.7.1: Bus 001 Device 068: ID 5345:1234 Owon PDS6062T Oscilloscope Negotiated speed: Full Speed (12Mbps) Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 0 [unknown] bDeviceSubClass 0 [unknown] bDeviceProtocol 0 bMaxPacketSize0 64 idVendor 0x5345 Owon idProduct 0x1234 PDS6062T Oscilloscope bcdDevice 1.00 iManufacturer 1 oscilloscope iProduct 2 oscilloscope iSerial 3 oscilloscope bNumConfigurations 1 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 0x0029 bNumInterfaces 1 bConfigurationValue 1 iConfiguration 0 bmAttributes 0x80 (Bus Powered) MaxPower 100mA Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 2 bInterfaceClass 5 Physical Interface Device bInterfaceSubClass 0 [unknown] bInterfaceProtocol 0 iInterface 0 ** UNRECOGNIZED: 09 21 11 01 00 01 22 5f 00 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x81 EP 1 IN bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0040 1x 64 bytes bInterval 32 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x01 EP 1 OUT bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0040 1x 64 bytes bInterval 32 Device Status: 0x0000 (Bus Powered) OWON appears to be using the same USB Vendor and Product ID for many of their oscilloscopes. Looking at the discussion about the USB vendor/product ID, in the link bellow, suggests that this VID/PID is shared with VDS, SDS, PDS, and now the HDS series oscilloscopes. Available documentation for these devices seems to indicate that all use a similar SCPI protocol, some with RS232 options. It is likely that this same simple serial setup would work correctly for them all.

2025-04-10USB: serial: ftdi_sio: add support for Altera USB Blaster 3Boon Khai Ng2-0/+27
commit 18e0885bd2ca738407036434418a26a58394a60e upstream. The Altera USB Blaster 3, available as both a cable and an on-board solution, is primarily used for programming and debugging FPGAs. It interfaces with host software such as Quartus Programmer, System Console, SignalTap, and Nios Debugger. The device utilizes either an FT2232 or FT4232 chip. Enabling the support for various configurations of the on-board USB Blaster 3 by including the appropriate VID/PID pairs, allowing it to function as a serial device via ftdi_sio. Note that this check-in does not include support for the cable solution, as it does not support UART functionality. The supported configurations are determined by the hardware design and include: 1) PID 0x6022, FT2232, 1 JTAG port (Port A) + Port B as UART 2) PID 0x6025, FT4232, 1 JTAG port (Port A) + Port C as UART 3) PID 0x6026, FT4232, 1 JTAG port (Port A) + Port C, D as UART 4) PID 0x6029, FT4232, 1 JTAG port (Port B) + Port C as UART 5) PID 0x602a, FT4232, 1 JTAG port (Port B) + Port C, D as UART 6) PID 0x602c, FT4232, 1 JTAG port (Port A) + Port B as UART 7) PID 0x602d, FT4232, 1 JTAG port (Port A) + Port B, C as UART 8) PID 0x602e, FT4232, 1 JTAG port (Port A) + Port B, C, D as UART These configurations allow for flexibility in how the USB Blaster 3 is used, depending on the specific needs of the hardware design.

2025-03-13usb: gadget: Set self-powered based on MaxPower and bmAttributesPrashanth K1-5/+11
commit 40e89ff5750fca2c1d6da93f98a2038716bba86c upstream. Currently the USB gadget will be set as bus-powered based solely on whether its bMaxPower is greater than 100mA, but this may miss devices that may legitimately draw less than 100mA but still want to report as bus-powered. Similarly during suspend & resume, USB gadget is incorrectly marked as bus/self powered without checking the bmAttributes field. Fix these by configuring the USB gadget as self or bus powered based on bmAttributes, and explicitly set it as bus-powered if it draws more than 100mA.

commit d6b82dafd17db0658f089b9cdec573982ca82bc5 upstream. During probe, the TCPC alert interrupts are getting masked to avoid unwanted interrupts during chip setup: this is ok to do but there is no unmasking happening at any later time, which means that the chip will not raise any interrupt, essentially making it not functional as, while internally it does perform all of the intended functions, it won't signal anything to the outside. Unmask the alert interrupts to fix functionality.

2025-03-13usb: typec: ucsi: increase timeout for PPM reset operationsFedor Pchelkin1-1/+1
commit bf4f9ae1cb08ccaafbe6874be6c46f59b83ae778 upstream. It is observed that on some systems an initial PPM reset during the boot phase can trigger a timeout: [ 6.482546] ucsi_acpi USBC000:00: failed to reset PPM! [ 6.482551] ucsi_acpi USBC000:00: error -ETIMEDOUT: PPM init failed Still, increasing the timeout value, albeit being the most straightforward solution, eliminates the problem: the initial PPM reset may take up to ~8000-10000ms on some Lenovo laptops. When it is reset after the above period of time (or even if ucsi_reset_ppm() is not called overall), UCSI works as expected. Moreover, if the ucsi_acpi module is loaded/unloaded manually after the system has booted, reading the CCI values and resetting the PPM works perfectly, without any timeout. Thus it's only a boot-time issue. The reason for this behavior is not clear but it may be the consequence of some tricks that the firmware performs or be an actual firmware bug. As a workaround, increase the timeout to avoid failing the UCSI initialization prematurely.

2025-03-13usb: atm: cxacru: fix a flaw in existing endpoint checksNikita Zhandarovich1-6/+7
commit c90aad369899a607cfbc002bebeafd51e31900cd upstream. Syzbot once again identified a flaw in usb endpoint checking, see [1]. This time the issue stems from a commit authored by me (2eabb655a968 ("usb: atm: cxacru: fix endpoint checking in cxacru_bind()")). While using usb_find_common_endpoints() may usually be enough to discard devices with wrong endpoints, in this case one needs more than just finding and identifying the sufficient number of endpoints of correct types - one needs to check the endpoint's address as well. Since cxacru_bind() fills URBs with CXACRU_EP_CMD address in mind, switch the endpoint verification approach to usb_check_XXX_endpoints() instead to fix incomplete ep testing.

2025-03-13usb: renesas_usbhs: Flush the notify_hotplug_workClaudiu Beznea1-0/+2
commit 552ca6b87e3778f3dd5b87842f95138162e16c82 upstream. When performing continuous unbind/bind operations on the USB drivers available on the Renesas RZ/G2L SoC, a kernel crash with the message "Unable to handle kernel NULL pointer dereference at virtual address" may occur. This issue points to the usbhsc_notify_hotplug() function. Flush the delayed work to avoid its execution when driver resources are unavailable.

2025-03-13usb/gadget: f_midi: Replace tasklet with workDavidlohr Bueso1-5/+7
[ Upstream commit 8653d71ce3763aedcf3d2331f59beda3fecd79e4 ] Currently a tasklet is used to transmit input substream buffer data. However, tasklets have long been deprecated as being too heavy on the system by running in irq context - and this is not a performance critical path. If a higher priority process wants to run, it must wait for the tasklet to finish before doing so. Deferring work to a workqueue and executing in process context should be fine considering the callback already does f_midi_do_transmit() under the transmit_lock and thus changes in semantics are ok regarding concurrency - tasklets being serialized against itself.

2025-03-13usb: dwc3: Fix timeout issue during controller enter/exit from halt stateSelvarasu Ganesan1-0/+34
[ Upstream commit d3a8c28426fc1fb3252753a9f1db0d691ffc21b0 ] There is a frequent timeout during controller enter/exit from halt state after toggling the run_stop bit by SW. This timeout occurs when performing frequent role switches between host and device, causing device enumeration issues due to the timeout. This issue was not present when USB2 suspend PHY was disabled by passing the SNPS quirks (snps,dis_u2_susphy_quirk and snps,dis_enblslpm_quirk) from the DTS. However, there is a requirement to enable USB2 suspend PHY by setting of GUSB2PHYCFG.ENBLSLPM and GUSB2PHYCFG.SUSPHY bits when controller starts in gadget or host mode results in the timeout issue. This commit addresses this timeout issue by ensuring that the bits GUSB2PHYCFG.ENBLSLPM and GUSB2PHYCFG.SUSPHY are cleared before starting the dwc3_gadget_run_stop sequence and restoring them after the dwc3_gadget_run_stop sequence is completed.

commit db79e75460fc59b19f9c89d4b068e61cee59f37d upstream. MeiG Smart SLM828 is an LTE-A CAT6 modem with the mPCIe form factor. The "Cls=ff(vend.) Sub=10 Prot=02" and "Cls=ff(vend.) Sub=10 Prot=03" interfaces respond to AT commands. Add these interfaces. The product ID the modem uses is shared across multiple modems. Therefore, add comments to describe which interface is used for which modem.

2025-03-13usb: cdc-acm: Fix handling of oversized fragmentsJann Horn1-1/+1
commit 12e712964f41d05ae034989892de445781c46730 upstream. If we receive an initial fragment of size 8 bytes which specifies a wLength of 1 byte (so the reassembled message is supposed to be 9 bytes long), and we then receive a second fragment of size 9 bytes (which is not supposed to happen), we currently wrongly bypass the fragment reassembly code but still pass the pointer to the acm->notification_buffer to acm_process_notification(). Make this less wrong by always going through fragment reassembly when we expect more fragments. Before this patch, receiving an overlong fragment could lead to `newctrl` in acm_process_notification() being uninitialized data (instead of data coming from the device).

2025-03-13usb: cdc-acm: Check control transfer buffer size before accessJann Horn1-3/+14
commit e563b01208f4d1f609bcab13333b6c0e24ce6a01 upstream. If the first fragment is shorter than struct usb_cdc_notification, we can't calculate an expected_size. Log an error and discard the notification instead of reading lengths from memory outside the received data, which can lead to memory corruption when the expected_size decreases between fragments, causing `expected_size - acm->nb_index` to wrap. This issue has been present since the beginning of git history; however, it only leads to memory corruption since commit ea2583529cd1 ("cdc-acm: reassemble fragmented notifications"). A mitigating factor is that acm_ctrl_irq() can only execute after userspace has opened /dev/ttyACM*; but if ModemManager is running, ModemManager will do that automatically depending on the USB device's vendor/product IDs and its other interfaces.
