No idea. If by pen drive you mean those USB memory sticks I heard that
it was quite difficult. There are micro controllers with built-in USB
features (TUSB series from TI?).

Anyway, SD card memory might be a lot easier if you are just after lots
of storage space.

Relatively difficult, but not impossible, to roll your own. The USB
clients in the pen drives have to talk to a protocol stack in a USB
host, i.e., normally a PC.

There are vendors that have such things for embedded processors.

Search for "embedded usb host" or similar.

I've seen some ARMs have USB host capabilities. For example the Atmel
AT91RM9200 has such a capability. I've seen some projects where people
emulated USB devices (for example, here: http://cesko.euro-
science.net/IgorPlugUSB/IgorPlug-USB%20(AVR)_eng.htm) but my understanding
is that emulating the usb host interface is a good deal more complicated -
so you'd probabaly have to go with a faster chip. Best of luck!
