Q: PC to PC thru USB ?

Hi all,

Is there a way to connect two PCs together
via their USB to exchange data between them ?

Do I just have to plug a USB cable, and
write a piece of code to make it run,
just like I've done for the RS232 ?

Do USB ports open like COM ports on a PC ?

TIA

USB networking device. The range from 20 to 25 bucks. Don't know if
it's USB 2.0 or 1.1. Load CD drivers, and start swapping programs,
files, etc between computers.

This is one great company, they ship USPS Priority Mail and their
shippingrates are very decent! Once you get their catalog, you'll be
hooked...they have so much computer stuff that's hard to get anywhere!
No, I'm not a cyberguy but a devoted customer. Spent a lot of bucks

USB stands for Universal Serial Bus, note the "Bus". The flow of data is
through a protocol, not Tx/Rx pins on a serial port. BTW, you also cannot
control the data on the PCI bus.

So ... It means I can't control the USB Host (Host controller) to
response others and works like a USB device(Function controller) ?

I formerly thought I could just modify the driver of host controller
to reply some standard token issues from other USB hosts and then I
could change the host controler behavior to work like a USB device.
So, it sounds I am too innocent. Right ?

I know the driver behavior of USB Host Controller is very complicated.
Maybe it is too difficult to change its behavior.
