Hi, I have an ricoh rdc7 digitalcam and want to write a linux-usb-driver for it with javaxusb. I have the Java 2 Standard Edition (build 1.3.1_04-b02) with the latest javaxusb compiled from cvs, and SuSE 8.1 with kernel 2.4.19.
The device has only one interface and one configuration and I can use it without any problems. But it have 4 endpoints: an input+output bulk and a interrupt-in + bulk-out. I can use the pipe of the bulk-output-emdpoint and can send a command to the camera with syncSubmit(byte[]) (I got that command with usbsnoop). Ok, the camera reacts, shows me the last picture on the display, like on windows. But according to usbsnoop it sends immediatly an ack, but if I try to read it with syncSubmit(byte[]) on the other pipe nothing happens. I got also an error-msg on /var/log/messages: Jun 9 21:47:03 Benjamin kernel: usb.c: USB disconnect on device 71 Jun 9 21:47:07 Benjamin kernel: hub.c: USB new device connect on bus1/2, assigned device number 72 Jun 9 21:47:07 Benjamin kernel: usb.c: USB device 72 (vend/prod 0x5ca/0x2201) is not claimed by any active driver. Jun 9 21:47:24 Benjamin kernel: usbdevfs: process 4286 (java) did not claim interface 0 before use Jun 9 21:47:24 Benjamin kernel: usbdevfs: process 4286 (java) did not claim interface 0 before use Jun 9 21:47:51 Benjamin kernel: usbdevfs: process 4337 (java) did not claim interface 0 before use Jun 9 21:47:54 Benjamin kernel: usb_control/bulk_msg: timeout Jun 9 21:47:54 Benjamin kernel: usbdevfs: process 4337 (java) did not claim interface 0 before use But I claimed that interface before and isClaimed() returns true. I tried also the other endpoints: on the other bulk-out, I can send what I want, the camera shows for a short time a black picture, on the interrupt-in-endpoint comes also nothing. I tested various combinations of it, and get no vaild data from the inputpipes. Is it perhaps a bug in javaxusb or in the kernel? Can anybody help me with it? Or perhaps tell me what I can test?
