AVR-Chat

Hai,
I am trying to make a usb host using atmel microcontroller. Actually I want to read the datas of pen drive by atmel microcontroller without using any computer. But main problem is I cannot find any firmware to make the microcontroller as a usb host.

If you want to make a usb device u can use v-usb (http://www.obdev.at/vusb/) firmware. But what to do to make a usb host? Anyone has any idea please?

Some AVR chips (e.g. AT90USB1287) have limited host capability referred to as OTG (On The Go).  The smaller/older USB devices don't have this capability.  You might look at the LUFA project to see what host capabilities it supports on host-capable chips.

Check out LUFA from Dean Camera aka abcminiuser.
