USB Smartcard reader unter L4Linux

[Gianfranco Ricci]

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".

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

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!
