Linux users, what is your V-USB device description?

Post by 8bitboy » Wed Dec 21, 2011 7:20 pm

Hi

I got V-USB working on an ATmega2560, however, before I post a description, one thing isn't quite right. When people plug-in their V-USB device under Linux, what Vendor name and product description do you get?

I tested LEDControl and PowerSwitch examples. Using 'lsusb', the Vendor name and description are annoyingly reported as " VOTI shared ID for use with libusb ".
So I modified them to connect to my device using only the VID & PID, which works.
When plugged-in to a WinXP PC, the device description is correctly read.... "Found new device: LEDControl"

I guess it must be something to do with how Ubuntu is attaching this device....

Thanks,
David.

I'm very sure I've used my V-USB project with Ubuntu Linux 10.10 with proper Vendor and Product stings. But I haven't checked lsusb. I was using libusb to talk to my device as done in a few examples.

Run

Code: Select all

dmesg
immediately after connecting your vusb device.
You will be able to see the correct Description.

Code: Select all

lsusb
displays either VOTI or VOTI shared ID for use with libusb depending on the VID and PID of the VUSB device.
