I believe it is 127 devices per controller, including hubs (7-bit address with one reserved address). Investigate the star topology in the USB 2 spec, which will make getting this many devices on one network a little difficult, but you might have more than one USB controller in the computer. I think bandwidth is divided among devices, so your capture rate for this many 10MP cameras may be slow? -Owen On Apr 13, 2010, at 1:53 PM, Daniel DeCovnick wrote: > Isn't USB limited to 63 devices per controller? > > -Daniel > > On Apr 13, 2010, at 4:59 AM, Aya Koshigaya wrote: > >> Hi, >> >> for a new project I need to capture 80 (!)
