Hi!

I want to connect USB GPS reciever to AVR micro. I have not dealt with USB, so I am wondering is it possible to use board with Silicon Laboratories CP2102 USB-UART converter.
As I understand one device has to be host.

Thanks in advance!

As the GPS is a USB device the AVr would have to be acting as a USB host. Any USB-UART converters are simply going to appear as a UART to an AVR and as a USB device to a PC (host) so they'd be of no use.

I believe the aim of "USB on the go" is to make devices that would normally just be devices capable of acting as hosts so you may want to research OTG chips to add to the AVR or I notice that AT90USB1287 and AT90USB647 are described as "on the go" too - may be worth a look?

As I understand Vinculum - Embedded USB Host Controller IC VNC1L device is acting as host, so I have to use ir or look for these USB ic

I would be very interested to hear what you find out and how you get on with the Viniculum chip.

It's something I have just been talking to a colleague about. We have a couple of prospective applications where chatting as a USB host would be v. useful.

There are also AVR's that can work as USB host for On The Go projects (OTG), like AT90USB1287.
