hello all!
when i try to open a 2nd device within my program, i get a problem when i claim the interface. The errorcode says "busy". i do the following: --Device A--- 1) select the device list. 2) open the device of interest 3) and claim the interface 0. 4) release the device list using 1 for the scnd paramter to decrement the reference counter. --Device B--- 1) select the device list. 3) open the device of interest 4) and claim the interface 0. But here i get the error code "busy".

Probably interface 0 on device B has already been claimed by a kernel driver. You will have to detach that other driver before you can claim the interface.
