Hi all, I am not sure this is the the right place for my question ... but this is the problem. I have an application for printing labels on CD/DVD discs. For this task I use a device composed by a mechanical arm for getting discs from a bin and putting it in an inkjet printer (the device has a CD writer too). The CD Writer and the Arm-printer) are independent devices and are connected to an USB hub. The Arm device is a Class Printer device and I send it commands using usb_bulk_write() and read its status using usb_bulk_read(). My application works fine on FC2 with the kernel 2.6.10-1.771 (the last available for FC2) but I need to move to FC5 (kernel 2.6.18-1-2200) for best support of SATA discs. I have recompiled the application on FC5 but when I arrive at the point where I send the data for printing, the device stalls and all successive calls to usb_bulk_write() fail with -110 and some time -2. I already had this problem in the past, but with kernel 2.6.10-1.771 it seemed resolved, now it reappears again. I should like to solve this problem but I don't know if the problem is in libusb, in the kernel or in the device. I suppose in the kernel because installing kernel 2.6.10-1.771 on the same workstation and using the same device it works.
Could you give me any suggestion ? Do you think it is possible to use the usbcore of kernel 2.6.10-1.771 in kernel 2.6.18-1-2200 or I should get some log message and submit to this mailing list ? In this case can you tell me the best way for getting this logs ? Thank you in advance.
