Hello,
I have a Trust CA-2100 USB2 5.25"external drive enclosure with a 40G
Maxtor hard disk in it. When I plug the device, it's seen fine. I can
mount the drive and read it just fine too. When I write to it though, it
goes okay for several seconds, then the drive light goes off, data
transfer stops, and I get this kernel messages in the log, repeated over
and over every 2 or 3 minutes:
May 7 17:03:42 akula kernel: usb 4-4: reset high speed USB device using
address
2
Eventually I kill the file copy, the kernel slowly flushes whatever was
left to write, and after several minutes, the drive light goes back on
and I everything is back to normal, unless I start a mass write again of
course.
If I remove ehci_hcd, operations to this drive fall back to uhci_hcd in
"full speed" mode (i.e. not USB2 high speed) and everything works
perfectly, albeit at a glacial pace. I've tried to use another USB
cable, plug it directly on the motherboard's USB sockets, recompiling a
new kernel, etc... to no avail.
Anybody has any idea what the problem might be? I'll probably bring it
back to the store and exchange it for a similar product from another
maker, but just in case I'm missing something, I thought I might ask first.
