To determine if the problem is w/ your device run usbview and check if your device sent all descriptors correctly.

And what, when USBasp is visible in windows, and in Linux not? usbview doesn't see this device.. My fellow have such a sytuation.. Any ideas?

EDIT: dmesg output after connect and disconnect USBasp:
"usb 3-1: new low speed USB device using uhci_hcd and address 2
usb 3-1: configuration #1 chosen from 1 choice
usb 3-1: USB disconnect, address 2"

On windows programmer works fine..
