LOOSING USB Connection

Post by Tobi_the_freak » Thu Jan 26, 2012 7:46 pm

Hi i have Problems with my selfmade usb- modul. I use the vusb-modul with an atmega8 and for controlling the modul i use the java version of libusb. and it works. but i have the problem that after some time (and the time is always different) i loose the connection from the pc to the modul. after plugging out and plugging in again and the re connection it works, but i dont want to replug it, cause the modul should send the data contiounsly.

For my program i used the custom-classs example with endpoint 0 from the package

DO u have a similar porblem or a solution for the problem?

Any chance the PC goes into some hibernation or powersaving mode? USB supports that but V-USB doesn't.
