I recently had a hard disk scratch and had to recreate my javax-usb
development setup. I have a program which communicates w/ a USB
connected GPS.
I have checked and my device nodes are mode 0666, and everything else
seems to work - program finds jar files, properties, etc. But I get a
failure (errno 28) when calling UsbPipe.syncSubmit().
The code snippet looks like:
/**
* read some bytes
*/
private GarminPkt readPkt(String name, UsbPipe usbPipe)
throws UsbException, IOException {
// get packet data
byte[] bytes = new byte[1024];
if (getVerbose() >= 2) {
System.err.println(name + ": blocking" + "\n");
}
int len = usbPipe.syncSubmit(bytes);
...
This all worked before (many times), but I did re-install Linux, java,
javax-usb, etc. and I wonder if I forgot something.
Any help would be appreciated. Thanks,
Tom Zepf
