Subject: libusb broken on 2.6.28 x86_64 ?
Date: Fri, 02 Jan 2009 01:31:08 -0500	[thread overview]
Message-ID: <495DB4AC.50602@rtr.ca> (raw)

I'm trying to use 2.6.28 for the first time on an x86_64 box here
with devices controlled by libusb.  The devices work on the first
access, but then fail on all subsequent accesses.  Unplugging/replugging
causes them to work again for a single subsequent access.

This is with two completely different USB gadgets:
a VFD alphanumeric display, and an FTDI serial device in bitbang mode.

Did something break in 2.6.28 for libusb devices ??

Cheers
