That is a _very_ old kernel. I suggest you upgrade to a newer one if you want support from the opensource community. > When i insert the USB smart card reader(VID/PID 04e6,4116),I get the > following message in the system log after starting klogd.(The driver > is not loaded) > > Nov 25 18:07:32 myPDA syslog.debug klogd: usbdevfs: USBDEVFS_CONTROL > failed dev 2 rqt 128 rq 6 len 18 ret -110 > Nov 25 18:07:32 myPDA syslog.warn klogd: usb_control/bulk_msg: timeout > Nov 25 18:07:32 myPDA syslog.debug klogd: usbdevfs: USBDEVFS_CONTROL > failed dev 2 rqt 128 rq 6 len 18 ret -110 > Nov 25 18:07:32 myPDA syslog.warn klogd: usb_control/bulk_msg: timeout > Nov 25 18:07:32 myPDA syslog.debug klogd: usbdevfs: USBDEVFS_CONTROL > failed dev 2 rqt 128 rq 6 len 18 ret -110 > Nov 25 18:07:32 myPDA user.notice /etc/hotplug/usb.agent: Setup cannot > get config descriptor: Connection timed out for USB product > 4e6/5115/416 This is the usbmodules utility.
