Hello,

I have exactly the same problem, it all works fine with RedHat 9.0(kernel version 2.4), but i get the same error with Fedora Core release 2, kernerl version(2.6).
Did some one manage to get a solution to this problem?
Regards,
André


Very strange. Can you try editing your javax.usb.properties file and enable JNI debugging? It may help determine what the problem is...

Hello,

Iam trying to submit data to a device (Card reader) suing syncSubmit(). Now
this program works perfectly fine when I execute it in Mandrake linux 9.1,
kernel version 2.4. But when I try to execute the same program for Fedora
Core release 2, kernel version 2.6.5, it fails. I get the error  Error
submitting IRP :Invalid, which is as follows:

javax.usb.UsbException: Error submitting IRP : Invalid at

com.ibm.jusb.os.linux.LinuxDeviceProxy$1.run(LinuxDeviceProxy.java:87)
      at java.lang.Thread.run(Thread.java:534)


Do you think there could be some problem/incompatibility with linux kernel version 2.6 that causes syncSubmit() function not to work??

Can anybody give me some suggestions? Thanks a lot!!
