/class/input/input4, HID, that means it was attached (or a part of it) as an input device.
CPU frequency doesn't change, and HID devices shouldn't alter frequency.
It's most probably the LEDs as SpeedEvil said.
It's also a plain HDD, nothing that should cause 'boost' events.

If you're providing your own vbus with an Y-cable, then it surely is, as the only it does now is toggle the twl4030 vbus pump (this is exactly what I was talking about when I said "play your cards well" in my previous post ;P ).

The 'input' driver is used by ondemand cpufreq scaling governor to boost CPU frequency immediately after some input event happens - you press unlock, keyboard, touchpad or power button. Attachment of dynamic USB device pursues the same goal.

EDIT: without it the scaling governor boosts frequency only after 75millisec.

Can we use WiMax usb modem with this host mode? madwifi drivers theoretically can be easy compiled for N900.

bme don't destroy vbus , simply bme have no idea ( and code ) about vbus and host mode status.
code is written only for charging mode not charge or boost vbus
no, there was nothing attached to the USB port. This is also confirmed by the value 0x00 read from the status register (no charge in progress, no charge done).

No Y cable here
(The cable was for the HDD, which I tried after testing if echo host is necessary or not)

Bad quality (10MP cameras these days...), but you get the idea (E: yellow light was solid when the drive was connected)

The drive spun up using the N900's power alone (then it went back to a slow quiet spin), but it was detected using the N900's port solely.
Connected it to the PS3 to get more power (which kicked it back into speed - still though, nothing in /dev)
However it didn't show up as a node in /dev, so I couldn't mount it.

E: Also tried a Wireless-N Wi-Fi USB adapter, it didn't power up but I have two guesses:
1. It's using too much power
2. It causes a kernel panic on my PC, so it might be borked

E2: Connecting the AC charger and running the pcsuite-enable.sh script causes the "Connected to USB device" dialog to pop up.

Looks wonderful, but what does these advancements here really mean if we speak just about reading/writing simple usb-stick?

- Do I need to patched kernel?
- What hardware/cables do I need
-- Does it matter how fast / on what order I connect cables+stick
- Is it mounted automatically
-- is fat32 the safest bet?

- Yes, patches above.
- Only an F-F adapter and the stock USB cable.
- It's just a bug at the moment that requires a connection to a PC first, fixing the driver should make it work without a PC.
- No, not at the moment
- File system doesn't matter, all should work, as long as the N900 supports them
