Camera on RS232 =? Micro-USB module + WebCam

Hi,

I recently saw a Micro-USB module on Dontronics's web site 
(http://www.dontronics.com/micro-usb.html). Appearently it convert RS232 to 
USB and vice versa.

Would it possible (how) to use this Micro-USB module con connect and an 
off-the shelf USB webcam  to a micro controller such as ATMega or PIC?
(I do not need high speed or high resolution images)

No.  Because Micro-USB module and a webcamera are both USB devices, and 
you would need a USB host.

Does anyone make a USB host module?  I couldn't find one the last time I 
looked.

Take a look at the CMUcam, it already outputs serial and may fit your needs.
http://www.cs.cmu.edu/~cmucam/

I've not used this product, but it resembles some designed-in-house 
camera boards I've used that worked rather nicely.

Later,

OTOH, if you need a serially-connected camera, look at the Wincam Live from
StarDot technologies - http://www.stardot-tech.com/wincam_live/

I've had one for ages, and did a port of support software to OS/2 - StarDot
was
very good about providing specs, protocol information etc.

The STV0680B chip from ST that is used in numerous cheapo webcams has an
RS232 interface, although not for tethered video. You may have to dismantle
a webcam and add a RS232 driver.
