I am using an ATtiny45 with V-USB. On Windows and Linux it works very fine but if i use an USB 1.1 Hub the device wont be recognized reliably in both operating systems. Does anybody have an idea

This may have something to do with voltage levels or it may be more complex. But it's hard to say without a capture of the on-the-wire communication.

Hello Tweety955,
I am using an ATmega8 with "vusb-20100715" and my OS is LinixMint10.
I can plug the Device in my USB1.1 "SunyLine 4xHub" and it works!
Firmware: /vusb-20100715/examles/hid-custom-rq
