Hi Oliver,
I was working with this JMicron device and using the uas driver.
I am seeing the following 2 issues.
1) On connect I see the following messages.
xhci_hcd 0000:00:11.0: ERROR Transfer event for disabled endpoint or
incorrect stream ring
This was eliminated using the following scissor patch.
---------------------------------8<------------------------------------
[PATCH] usb: storage: unusual_uas: Add JMicron JMS56x to unusual device
This device gives the following error on detection.
xhci_hcd 0000:00:11.0: ERROR Transfer event for disabled endpoint or
incorrect stream ring
The same error is not seen when it is added to unusual_device
list with US_FL_NO_REPORT_OPCODES passed.

2) On disconnect I am seeing the following issue
scsi host4: uas_post_reset: alloc streams error -19 after reset
sd 4:0:0:0: [sdb] Synchronizing SCSI cache
This is more fatal because after these messages the USB port becomes
unusable. Even an lsusb invocation hangs for ever.
Also please note that the device works fine with usb-storage driver.
I am attaching the usbmon capture of disconnect using uas and
usb-storage driver.
Any help in this regard is highly appreciated.
Regards,
-George
