USB: storage: Add quirks for Entrega/Xircom USB to SCSI converters

2014-12-01T10:02:35+00:00

commit c80b4495c61636edc58fe1ce300f09f24db28e10 upstream. This patch adds quirks for Entrega Technologies (later Xircom PortGear) USB- SCSI converters. They use Shuttle Technology EUSB-01/EUSB-S1 chips. The US_FL_SCM_MULT_TARG quirk is needed to allow multiple devices on the SCSI chain to be accessed. Without it only the (single) device with SCSI ID 0 can be used. The standalone converter sold by Entrega had model number U1-SC25. Xircom acquired Entrega and re-branded the product line PortGear. The PortGear USB to SCSI Converter (model PGSCSI) is internally identical to the Entrega product, but later models may use a different USB ID. The Entrega-branded units have USB ID 1645:0007, as does my Xircom PGSCSI, but the Windows and Macintosh drivers also support 085A:0028. Entrega also sold the "Mac USB Dock", which provides two USB ports, a Mac (8-pin mini-DIN) serial port and a SCSI port. It appears to the computer as a four-port hub, USB-serial, and USB-SCSI converters. The USB-SCSI part may have initially used the same ID as the standalone U1-SC25 (1645:0007), but later production used 085A:0026. My Xircom PortGear PGSCSI has bcdDevice=0x0100. Units with bcdDevice=0x0133 probably also exist. This patch adds quirks for 1645:0007, 085A:0026 and 085A:0028. The Windows driver INF file also mentions 085A:0032 "PortStation SCSI Module", but I couldn't find any mention of that actually existing in the wild; perhaps it was cancelled before release?

USB: storage: Add quirk for Ariston Technologies iConnect USB to SCSI adapter

2014-12-01T10:02:35+00:00

commit b6a3ed677991558ce09046397a7c4d70530d15b3 upstream. Hi, The Ariston Technologies iConnect 025 and iConnect 050 (also known as e.g. iSCSI-50) are SCSI-USB converters which use Shuttle Technology/SCM Microsystems chips. Only the connectors differ; both have the same USB ID. The US_FL_SCM_MULT_TARG quirk is required to use SCSI devices with ID other than 0. I don't have one of these, but based on the other entries for Shuttle/ SCM-based converters this patch is very likely correct. I used 0x0000 and 0x9999 for bcdDeviceMin and bcdDeviceMax because I'm not sure which bcdDevice value the products use.

USB: storage: Add quirk for Adaptec USBConnect 2000 USB-to-SCSI Adapter

2014-12-01T10:02:34+00:00

commit 67d365a57a51fb9dece6a5ceb504aa381cae1e5b upstream. The Adaptec USBConnect 2000 is another SCSI-USB converter which uses Shuttle Technology/SCM Microsystems chips. The US_FL_SCM_MULT_TARG quirk is required to use SCSI devices with ID other than 0. I don't have a USBConnect 2000, but based on the other entries for Shuttle/ SCM-based converters this patch is very likely correct. I used 0x0000 and 0x9999 for bcdDeviceMin and bcdDeviceMax because I'm not sure which bcdDevice value the product uses.

xhci: Fix null pointer dereference if xhci initialization fails

2014-12-01T10:02:30+00:00

commit c207e7c50f31113c24a9f536fcab1e8a256985d7 upstream. If xhci initialization fails before the roothub bandwidth domains (xhci->rh_bw[i]) are allocated it will oops when trying to access rh_bw members in xhci_mem_cleanup().

storage: Add single-LUN quirk for Jaz USB Adapter

2014-12-01T10:02:30+00:00

commit c66f1c62e85927357e7b3f4c701614dcb5c498a2 upstream. The Iomega Jaz USB Adapter is a SCSI-USB converter cable. The hardware seems to be identical to e.g. the Microtech XpressSCSI, using a Shuttle/ SCM chip set. However its firmware restricts it to only work with Jaz drives. On connecting the cable a message like this appears four times in the log: reset full speed USB device number 4 using uhci_hcd That's non-fatal but the US_FL_SINGLE_LUN quirk fixes it.

usb: hub: take hub->hdev reference when processing from eventlist

2014-12-01T10:02:29+00:00

commit c605f3cdff53a743f6d875b76956b239deca1272 upstream. During surprise device hotplug removal tests, it was observed that hub_events may try to call usb_lock_device on a device that has already been freed. Protect the usb_device by taking out a reference (under the hub_event_lock) when hub_events pulls it off the list, returning the reference after hub_events is finished using it.

usb: host: xhci: fix compliance mode workaround

2014-12-01T10:02:27+00:00

commit 96908589a8b2584b1185f834d365f5cc360e8226 upstream. Commit 71c731a (usb: host: xhci: Fix Compliance Mode on SN65LVP3502CP Hardware) implemented a workaround for a known issue with Texas Instruments' USB 3.0 redriver IC but it left a condition where any xHCI host would be taken out of reset if port was placed in compliance mode and there was no device connected to the port. That condition would trigger a fake connection to a non-existent device so that usbcore would trigger a warm reset of the port, thus taking the link out of reset. This has the side-effect of preventing any xHCI host connected to a Linux machine from starting and running the USB 3.0 Electrical Compliance Suite because the port will mysteriously taken out of compliance mode and, thus, xHCI won't step through the necessary compliance patterns for link validation. This patch fixes the issue by just adding a missing check for XHCI_COMP_MODE_QUIRK inside xhci_hub_report_usb3_link_state() when PORT_CAS isn't set. This patch should be backported to all kernels containing commit 71c731a. Fixes: 71c731a (usb: host: xhci: Fix Compliance Mode on SN65LVP3502CP Hardware) Cc: Alexis R.

usb: dwc3: core: fix order of PM runtime calls

2014-12-01T10:02:26+00:00

commit fed33afce0eda44a46ae24d93aec1b5198c0bac4 upstream. Currently, we disable pm_runtime before all register accesses are done, this is dangerous and might lead to abort exceptions due to the driver trying to access a register which is clocked by a clock which was long gated. Fix that by moving pm_runtime_put_sync() and pm_runtime_disable() as the last thing we do before returning from our ->remove() method.
