Dear All,
I am new to the embedded linux development i am using a sa1100 based
PDA that runs 2.4.18-rmk7 kernel.
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

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
I hope this message is because the usb system did not get the
configuration descriptor for the device.But when i analysed with the
CATC analyser the configuration descriptor is actually sent from the
device to the host.
I compiled the USB Skeleton driver (usb-skeleton.c) with the VID PID
modifications for my device.
Then with the driver loaded (explicitly by insmod command)i got the
following oops
Nov 26 16:39:33 myPDA syslog.info klogd: hub.c: USB new device connect
