USB IR receiver issues

[Josh P. <jos...@Da...>]

I'm having run-time trouble with lirc on a new fc6 box.  I've tried both rpms 
from atrmps.net and a fresh 0.8.1 install from source, to no avail.  I'm using 
the ione Libra-Q11 remote and receiver, which should be compatible with 
lirc_mceusb2, but it seems like the lirc kernel modules are messing with the USB 
subsystem in some way.

When I physically plug in the receiver without the kernel modules installed, I 
get the following in /var/logs/messages:

Feb 13 05:01:50 hostname kernel: usb 1-2.1: reset full speed USB device using 
uhci_hcd and address 17
Feb 13 05:01:50 hostname kernel: usb 1-2.1.4: new full speed USB device using 
uhci_hcd and address 80
Feb 13 05:01:51 hostname kernel: usb 1-2.1.4: configuration #1 chosen from 1 
choice

Looks fine.  However, after installing lirc, plugging in the receiver yields the 
following:

Feb 13 05:08:19 hostname kernel: usb 1-2.1.4: new full speed USB device using 
uhci_hcd and address 82

This loop continues ad infinitum, with the device being recognized, then 4-7 
seconds later spontaneously being disconnected and reconnected.  lircd seems to 
run happily enough, but irw exits immediately after starting and takes down 
lircd with it.  For the record, the behavior is the same when plugging directly 
into the computer, rather than the hub shown here.

Has anyone seen this behavior?  I'm looking forward to solving this, so any help 
would be greatly appreciated.
