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.
Thanks. Do you want to submit it to Greg?
The patch is fine.
Yes please!!!
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.
Ouch. That points to a logic error. We should not reset if
a device is gone.
Could you send dmesg of such a case?
here is the dmesg!!

Above is the dmesg without the unusual_uas patch applied.
Do you need me to enable any specific dev_dbg and then the dmesg output?
Can you get us a dmesg with the unusual_uas patch applied? Usually once
things go foobar because
of issue-ing a command which the device does not understand, more things
typically come down
as both the device and the host may be in an undefined state then.
