What is the maximum number of USB 2.0 cameras on a single USB 2.0 bus?

High-performance digital cameras for industrial, scientific ...
In theory, you can have up to 127 USB 2.0 devices on one USB 2.0 bus. This value includes all hubs required to connect all the other USB 2.0 devices on the bus. Assuming you wanted to connect as many cameras as possible and you assume that each hub has 4 ports, you would be able to connect, in theory, up to 94 cameras using 33 hubs. In practicality though, we do not recommend connecting more than 4 at a time as the performance of each camera will be 1/2 of its max throughput.

To view the data, simply open any application into which you would normally type, (e.g., a word processor or spreadsheet). Scan the bar code and the data will appear as if it were typed in via the keyboard. My bar code scanner reads the sample codes for Code 39, but will not read the bar codes created with the bar code font on my PC.

I just connected my MPIII PC Interface and it does not seem to work, what's wrong?

Mesa Labs - DataTrace FAQs
The MPIII PC interface gets power from the serial port of the PC. However, because the optical emitters use more power for very brief periods than the PC can supply, the Interface stores energy in very large capacitors built into its circuitry. These capacitors make a total of 2 Farads, much more energy storage than conventional capacitors. Unlike batteries, these capacitors can charge and discharge over and over without wearing out, so they should never need to be replaced.
