Hi L4 Hackers, i have solved the problem after a lot of hours by myself. The problem is the 2.6.22-4 which neither have devFS nor udev so that /dev/bus/usb is not populated. But the directory is used by libusb. So libusb were not able to communicate the the devices and the driver for the smartcard reader could not be loaded. I tried a "hack" and now all works fine :-), lsusb shows all devices und the smartcard reader functions. I just tried a ln - s /proc/bus/usb /dev/bus/usb. I know thats some dirty hack, if someone has an nicer solution I would be happy to hear it. Gianfranco Gianfranco Ricci schrieb:

Hello l4hackers!

I'm trying to set up an L4Linux environment in which a USB smartcard reader [ReinerSCT cyberjack e-com(a) ] can be used but I'm encountering problems.

I'm using:

L4Linux 2.6.22 with complete USB support libusb 1.0 usbutils 0.11 Driver 3.3.2Beta3 for the smartcard reader PCSC-lite 1.53

The problem is that the driver could not be loaded (into USB userspace). Maybe the libusb (compiled under Linux 2.6.25) is not complete compatible with L4Linux 2.6.22. Using Blockdevices such exernal Harddisks is possible, so USB support in general should be okay.

Executing "lsusb" don't show ANY USB device. Only "lsusb -t" shows a correct result in which my cardreader is listed. Other parameter have the same output as "lsusb".

Using "cat /proc/bus/usb/devices" shows ALL devices (here listed only my smartcard reader)

When i try so start PCSC-Lite which should load the ReinerSCT driver the syslog tells:

and debug output from ReinerSCT driver:

Has anyone experience using a smartcard reader (or a usb device using userspace driver under L4Linux) ? Could the problem be the libusb compiled under Linux? Has anyone an other idea where the problem could come from?

Thanks in advance!
