Hi,
I need to interface lots of microcontrollers to a single Windows PC. How much - 100 pieces. All of them have UART, of course; but USB is not available. I was wondering if I can use 11 USB Hubs, each with 10 output ports connected in daisy chain.

1to10 USB HUB

10x 1to10USB HUB

ch.1 ch.2 .... ch.100
Moreover every channel (from 1 to 100) would have a USB to UART converter (FTDI or PL). But I am asking myself if
1. A PC is capable to handle 100 virtual COM ports. (Theoretically it should be 127USB and 256COM ports)
2. 100 pieces of FTDI or PL chip can harmful work on one system...
Any ideas?
