I having and issue with usb barcode scanner that acts as a HID
device. It seems to have some timeout issue when it first comes up.
This on Fedora Core 5 (kernel 2.6.17-1.2187_FC5). Some times the
device eventually "connects" and starts working. I've tried several
different devices with the same results and on different machines
with similar results
Any ideas? Is there some way to extend the timeout period?
thanks
