Description Samuel Thibault 2006-05-07 18:49:42 UTC

Most recent kernel where this bug did not occur: 2.6.15
Distribution: debian
Hardware Environment: USB 1.1 hub
Software Environment: cat/minicom
Problem Description:
character transfer between pc and hp4x stopped working with kernel 2.6.16

Steps to reproduce:
plug hp4x device, start minicom, type characters in minicom or on hp4x, nothing appears on the other side.  With 2.6.15 it works ok.

I enabled debugging in the module, and attached is lsusb + dmesg
Note that the USBDEVFS_CONTROL errors in dmesg correspond to the "cannot read device status" error in lsusb
