USB Webcams with FLOSS firmware or FLOSS supporting vendors?

[Paul Menzel <pmenzel@xxxxxxxxxxxxx>]

Dear Linux folks,


USB Webcams are pretty well supported today, but can you recommend a 
model, where the firmware is available under a free license or the 
device is open hardware?

If these things do not exist, I’d like to buy a model, whose vendor is 
supportive of the FLOSS drivers. Can you recommend a vendor, paying 
developers to contribute patches or at least provides test hardware?


Kind regards,

Paul
