You could narrow down about when it happens by adding -vvvv (four "v"s). Curious, what would be the advantage of CDC mode, anyway? Yes, I know that HID mode is a crock which has mainly been used since for Windows, all the USB world appears to look like a human interface -- because that's close to the only class of devices they can talk to without installing a vendor driver. But then, if you're on Linux, you've got libusb which can talk to any device, so why bother with a driver at all? -- cheers, J"org .-.-. --... ...-- -.. .
