Greg,

With 2.6.17-rc6-git2, I'm seeing this kernel message during start-up:

pl2303 ttyUSB0: pl2303_open - failed submitting interrupt urb, error -28

The pl2303 serial port is part of a USB1.1 Hub/dock device,
plugged into a USB2 port on my notebook.

I get the same failure again when trying to use the port with Kermit.
This device was working fine here not long ago -- on the -rc5 kernels I think.

Mmm.. no, it's broken in 2.6.17-rc5 as well.
I'll go back to 2.6.16.xx now, and see about that.


Unplugging the hub/dock does this:
