External card reader: worked with multiple cards simultaneously (e.g. Compact Flash + RS-MMC)
External HD: did NOT work when HD needed USB power. I tried to get power from the N800 and plugged a separate power plug into my powered hub. Did not work either way.
N95: Tried my Nokia N95 phone. Worked as a mass storage device; did not work when the device wanted PC suite (duh)
Web camera: nothing. THe N800 recognized the device as an unsupported one (aren't they all?) but this was really unsupported.

Make sure you guys are careful with any storage devices if trying to power directly from the N8X, most will need more than 100mA when actively transferring files, so I'd imagine file corruption is a possibility.

I tried an Ethernet adapter (3Com 3C19250 based) and it wasn't recognized. I would love to have Ethernet working, as we have WiFi locked down at work.

Any hope with HSDPA USB Modem ?

The "kaweth" kernel module might work:

Needs to be compiled, though.

  • Mass storage - works
  • HID - keyboards work, mice have same troubles as BT mice
  • CD/DVDs - has no drivers
  • Network adapters (Will power be an issue for some of these?)
    • Ethernet - Helpful, but do they work?
    • 802.11b/g - Redundant, probably less range
    • 802.11a,n - Could be helpful, do they work?
    • BT - Redundant, unless you need longer range... Then power draw probably kills you.
  • Serial adapters (including USB interface on HP49G+) - Probably no drivers?
  • Audio (USB speakers) - Not persuaded of utility, but might work. Probably no drivers?
Anything else?
Digital cameras. I guess they should work in mass storage mode, but will they work in PTP mode?

Re: N800 USB Host Mode Experiment
 
What are the architecture requirements for sourcing USB driver modules for OS 2008? Do they simply have to be compiled for ARM, ARM11, any TI OMAP, or specifically the OMAP 2420? Does the kernel version have to match exactly, or will any module compiled for a 2.6-series kernel work?

(please excuse my noobness :o )

are usb joysticks working? Would be great for lxdoom and emulators....

Re: N800 USB Host Mode Experiment
 
I'm praying that a USB ethernet adapter will work without extra power. I'll hate to be in a place without wifi but with ethernet when I get my N810.

If it does need extra power, how would I add it? I know of those battery hacks made to supply the right current, but how would it be plugged in to supply power? Are there cables that split the pins for power to a female plug--letting you plug in a power source via USB?

Re: N800 USB Host Mode Experiment
 
has anybody tried plugin an usb gps reciever to the N800?
i have the microsoft's universal from streets and trips but i lack an internet tablet(getting one on xmas).

in theory it should work because all you should have to do, is direct the gps software to switch coms...
