Trash messages from dmesg output. Be sure to use latest booston (provided by joerg_rw in this thread, few pages ago - You need to install it manually), and that You're choosing high-speed, if Your HUB is real 2.0 compliant, or Full-speed otherwise. Hub will manage connection speed for keyboard.

Also, You could first try to connect keyboard without any hubs, then start adding things, that may complicate debugging. As for extkbd, yea, Your keyboard should be recognized after enumerating, but it is unrelated to hostmode, and Your output clearly show errors on connection (USB) part, so leave further things alone for now.

Please, try executing everything in following order:

1. Choose appropriate speed for Your keyboard - low-speed or full-speed (most low-speed keyboards should work also with full-speed). Do *not* use high-speed, unless You're 100% sure, that You got strange keyboard that need it (most unlikely).

2. wait second or two, enable vbus booston (next step).

3. after 2 or three seconds, connect Your keyboard to N900 (it *musn't* be connected before!

4. Wait another few seconds, then choose "enumerate".

5. You should get message about connection - if not, open kernel messages, and post result here. If doing so, please be sure that You're posting here output only of this single attempt (i.e after fresh restart of H-E-N), to help us parse output quickly .

6. Ignore any messages about filesystem not available, they're irrelevant here.

7. If You cannot connect *anything* - be it keyboard, mouse, pendrive... That mean You've probably got something screwed on device software side. Most likely, kernel-power installation, or H-E-N one itself.

As for Your question about my desktop - I use WOL (wake on LAN) - after few lines of ssh tunnels for security - so I don't need to have desktop on all the time. But this is off-topic here, so PM me if You got any questions regarding this.

Good luck with H-E-N!
