lsusb and wifi adapter

[jbnhf23]

i am trying to setup my "sandberg micro wifi usb dongle".

When I perform a lsusb command the dongle is not listed.

Should the dongle always be listed when I perform a lsusb command?
- If yes, could it be a broken wifi adpater or ?
- if no, could someone give me some guidance that could lead me in the right direction

I am pretty new in this linux world...

best regards....jesper

This is why. Your adapter is not registering as it appears to be unreadable.

Does it work if you plug it into a PC USB port?

[jbnhf23]

yes it is working in my windows 7 laptop

Starting at line # 183 in your dmesg on pastebin you'll see a bunch of error messages

Is your device USB 1.1, USB 2.0 or USB 3.0?
Is your USB HUB 1.1 or USB 2.0 or USB 3.0?

[DougieLawson]

yes it is working in my windows 7 laptop

Can you use the the Windows control panel/device manager (run devmgmt.msc) to find the Vendor ID and Device ID?
