This looks like it would be interesting to do with a PIC

looks possible:

but I don't think you can run it on an 8-legged part :)

There are of course PICs with USB interface. As to 8 pins,

2 suply 2 USB 2 xtal 2 I/O makes 8 Not sure if the 8 pinners can do that frequency.

If you use the 2 I/O for RS232 in/out then you have an USB to RS232 converter. But I see no Linux driver on that site...

Ouch!!

The reason they use AVR is for the soft USB library. I don't think there's one for the PIC. You can use the hard USB, but more expensive than any AVR.

OK, i was wrong. I wish they have something newer than PIC16.

There are lots of PIC18 and PIC24 with a real USB engine.

Here is a DIY PIC18 project:

Yes, I noticed that this morning.

AS they say in the old country: Oh well.

This sure seems touchy to mux supply, xtal, usb and IOs one the same pin#2

What do they use the other seven pins for?

Thanks,

You need to follow the links:

is a Linux project.

This v-usb project is also HID, so Linux knows about it out of the box, no driver required.

look like it, just like v-usb, uses libusb that is a cross platform usb driver I believe it is CC license so you can just build it yourself

I had a go with libusb some years agao to try to make a Linux driver for my Canon USB scanner. Got about half way when the scanner dropped of the table, now makes funny noises, and I then stopped that project. The scanner still sort of works in win 98. Next one I will make sure it has a Linux driver. Likely will, as MS is making a loss this year, and companies will see the writing on the wall, (The End Of Windows), and make sure they have Linux soft. I have read that Blamer(sorry Freudian) BALMER now gets some Demonrattic publicity planning guy to oversee his stublings. Fun fun fun. And then they need to split MS up in an OS part and application part... Billy already mentioned that that would be the end IIRC. The MS news too kdown DJ a lot yesterday.

The point is that POLITICS does not make technological advances, it only uses those for its own purposes. MS has been making the same crap over and over again in an ever worse way ever since win 3.1. Keeping it going by integrating some apps..

Was I of topic? Oh well, If I needed an USB PIC I would use one with hardware USB. LOL But I try to avoid USB ... I like Ethernet, galvanic insulation.... Sure you need a supply, but being limited to a few 100 mA in case of USB is not always possible. And dongles? This thing described is just a dongle right? Not very nice things.

OK. :_) :-)

OK, so it thinks it is just an USB keyboard.
