Hi Alan, sorry for the delay. It took me a while to get back to this.

Since the device stopped working under windows, I'm guessing that it's simply broken. I'll try to get my hands on a new sample. The PSZ-HA50 and the PSZ-HA1T work nicely when attached to USB 3.0 with this setting: --- snip --- $ cat /sys/module/usb_storage/parameters/quirks 054c:087d:u --- snip --- W/o this quirk they do not work. I'd be surprised if a non-broken PSZ-HA2T behaved any differently. So perhaps you might want to consider adding that quirk directly into the Kernel? FTR, the PSZ-HC1T just worked. Thanks again!
