pl2303.ko and usbserial.ko are needed to connect any gadget through USB with a cable "USB to serial".
With this you can programme for your gadgets, transfer data, and control a lot of things.

The only you have to do is download usbserial.ko and pl2303.ko and type into n8X0 terminal (root):
insmod usbserial.ko
insmod pl2303.ko
and fun!

Thanks ! Maybe I could try this with my Psion Series5... :-)

Are you saying that a N800 can be a USB host controller? Can it supply power out the USB port?

Doug, this has been mentioned many times already, but to summarize: OS2008, which runs on both the N800 and the N810, has built-in USB host functionality. Basically, all is needed is a USB cable with a male end that fits into the N8X0, with pins 4 and 5 soldered together, and a female end to which you can connect any other device. In the N800's case, all you need is a Mini-AB (M) to Type A (F) cable, then cut (some of the) shielding from the Mini-AB end so that it fits into the connector on the tablet. Then just connect your USB keyboard or pendrive and the tablet will recognise it. If you connect a pendrive, it will even open the file manager to show you the files on it!

HTH.

EDIT: Yes, it _will_ supply power, but is limited to a maximum current of about 125 mA IIRC.

- w00t! you're darn' tootin', partner!

- this was the 'missing link' for me!

- now i'll be able to use my n800 to remotely control my high-frequency receiver (Ten-Tec RX-320)

- tks!

p.s. too bad we don't have 'line-in,' else we'd have gMFSK up and running for PSK31 ops!

I'm pretty sure the audio chip has line-in, but I don't think it's connected to anything

USB soundcards are not unheard of...

I'm aware of USB soundcards, I'd just prefer to have less junk dangling off the tablet.

I wish they had simply put a switch so we could toggle between line or mic level.

Maybe it is connected and there's some magical way to switch in software, but no one's confirmed or denied. It really bugs me to have hardware that I can't use (IVR, PowerVR(?), and line-input, at least)

- just verified that these modules appear (in the system at least) to work on my os2008 n800:

- next step is to build and test a command-line version of the Debian RX320 command-line client!

- tks to the OP!

Gave this a try with my Keyspan USA-19Qi USB-serial adapter, but it didn't seem to like it.

Took it apart. Inside was a Cypress AN2131SC chip.
