Hi Vladimir,
thanks for the info.
I wanted to try some experiments with this new version, but,
unfortunately, something is probably bad in trunk - there is no
accessible any disk device after "insmod <driver>" ("ls" does not list
any device, only empty line).
<driver> can be (maybe) anything, I tried ehci, uhci, ohci and (non USB
driver) ahci.
I.e., problem is not related to USB drivers only.
For the first look it sounds like there is maybe something wrong with
insmod command itself.
(I built GRUB from latest trunk on 64-bit Arch Linux.)
You have to use nativedisk command which reloads disk drivers all at
once as BIOS disk services are disables when *hci or pata is loaded.
BR,
Ales

Hi Vladimir,
- what was the reason of the OHCI problem on Loongson?
(I don't see any details of solution below nor the patch... ?)
It was bad handling of root ports. My standard system has only EHCI+RMH
so root port isn't accessible and is never hotplugged. This was
introduced by USB init speed-up series

I fixed the usb keyboard bug on fuloong. Looks like some "antivirus"
software blocked my message with GRUB binary. Also thers is grub.elf
(from 2.00~rc1) in downloads section.

OK, so it will be some another case.
There will be helpful additional information - does work USB at
all?
I.e. when You connect e.g. USB flasdisk, is it working, can You
use it
in GRUB?
(Sorry if it is not possible to try such situation, I never seen
loongson (fuloong) mini-pc...)
No, it does not work. pmon handles it correctly, but grub provides
the
error disk not found, :-(
Another thing - You mentioned You used OHCI GRUB driver. As I
see on
http://www.lemote.com/en/products/mini-computer/2010/0310/111.html ,
there is mentioned USB 2.0, i.e. it should be probably EHCI
controller
- ?
I also generated image including the ehci module, and it didn't make a
change...
(OHCI is USB 1.1 controller - but it could be used together with
USB 2.0
EHCI as so called companion controller).
Is it possible that Your Mini-PC has USB 2.0 only (i.e. EHCI)
controller
(without companion controller)?
Are somewhere available more detailed information about Your
loongson-2f
Mini-PC HW?
I'm attaching more information about the mini-pc... Notice dmesg
indicates linux used ohci for this device without problems:
