uasb3-sata-uasp1 on linux-3.15.1 is not working

Hi,

Tried your device plugable uasb3-sata-uasp1 on linux-3.15.1, It is not working with ubuntu. Seems that some of uasp- driver is not stable at all.
Can you tell me whether these devices has been tested on linux or not?

currently kernel 3.15.1 is trying to run this device with UAS module instead of usb-storage.

Hi Anil,

Thanks for the additional lspci information. As mentioned in the email we sent, we have done quite a bit of successful testing with Linux, but I’ll see if we’re able to reproduce your results focusing on the UAS module.

Thanks!
Gary

Hi Anil,

We haven’t encountered any issues testing with UAS in Ubuntu/3.15.1 this afternoon.

Can you please paste the output of “sudo lsusb -vvv” with all USB devices attached so we can see if there are any more clues?

A couple other questions:
-What type of issues are you encountering when the UAS module is loaded? Is it kernel panics like other UAS users have reported, or is the behavior different?

-Also, there’s a 3.15.5 update available - can you test to see if that improves the behavior?

Thanks!
Gary

one more thing Gary, After some time of inserting your device kernel crashes and my laptops checks for disk consistency and reboot.

meanwhile i m trying to run the same on linux-3.15.5, Will let u know the result.

Hi Anil,

Thanks for the additional output. Not seeing anything that is a likely-root cause of the issue.

Hopefully things will run better with 3.15.5 - please let us know after you’ve had a chance to test a bit with the new kernel.

Thanks!
Gary
