Problem rebooting into ALARM

usb - USB sub-system

Usage:
usb reset - reset (rescan) USB controller
usb stop [f] - stop USB [f]=force stop
usb tree - show USB device tree
usb info [dev] - show available USB devices
usb storage - show details of USB storage devices
usb dev [dev] - show or set current USB storage device
usb part [dev] - print partition table of one or all USB storage devices
usb read addr blk# cnt - read `cnt' blocks starting at block `blk#'

usb write addr blk# cnt - write `cnt' blocks starting at block `blk#'
from me
')

So this tells me what 'usb reset' does... But I still don't understand what you mean by 'doubling the usb reset command'.

I really am out of my depth at this point but trying my best to hang on... I'd be very grateful if you could give further advice. Thanks.

EDIT:

Issuing a 'usb reset' gives me:

$this->bbcode_second_pass_code('', '
Marvell>> usb reset
(Re)start USB...
USB: Register 10011 NbrPorts 1
USB EHCI 1.00
scanning bus for devices... 3 USB Device(s) found
scanning bus for storage devices... 0 Storage Device(s) found
')

EDIT2:

I do think we're onto something here. If I 'feel' the HDD I can physically feel it start to spin up when I issue usb reset. The issue is by the time it's really spun up the output '0 Storage Device(s)' is already displayed. I hope this might help...

EDIT3:

I have been playing with 'rootdelay' (and usb_rootdelay) and they certainly do not seem to be in seconds (e.g., 10 does not wait 10 seconds!) however it does seem, though I cannot be certain, that there are *tiny* changes in the time it 'usb reset' takes. Irrespective of this the drive always spins up as soon as the '0 Storage Device(s)' is shown. It's almost as if the device only spins up after the 'usb reset', though in fairness it may be that changing 'rootdelay' is not actually changing anything at all. I really don't know!

[WarheadsSE]

Great, now run that command a second time.

Also, this may be "out of your depth" but it will only become familiar if you try it. Manuals suck for actual knowledge You're learning why, not what

[LavaChild]

Thanks for your help. I do appreciate that this is making a positive learning experience and knowing now that I can access UBoot (and interact - on Windows) is very reassuring.

Back to the troubleshooting:

By 'run that command a second time' do you mean the 'usb reboot'? In which case, I tried (issued immediately after the output for the first command had finished) and the output was the same. What is odd (though I do not know if this is correct behaviour or not) is that after the drive spins up it then spins back down again...

[WarheadsSE]

E.g.
$this->bbcode_second_pass_code('', '
Marvell >> usb reset
...
Marvell >> usb reset')

If the output is still the same then
$this->bbcode_second_pass_code('', 'Marvell >> usb tree')

[LavaChild]

I believe I tried that but still '0 Storage Device(s)'. I did at one point do a 'usb tree' but don't have the output any longer.

Unfortunately I will be unable to investigate this further until sometime in the middle of next week now however I am very keen to continue debugging this and work to a solution. At the next available opportunity I will execute the all of the commands as in your last message and will post the output.

I'd like to quickly thank you for all of your prompt help and I hope you'll be able to continue to assist me when I can come back to this problem I'm slowly but surely learning and I do believe this is an interesting learning process. (Certainly I'm having much better luck than I ever did with a GuruPlug!).

[LavaChild]

I've finally had another chance to look at this. Output of usb reset, usb reset, usb tree, usb info below:

Any suggestions on what to try next?

Thank you!

And, for completeness, here is the output of usb reset, usb tree, usb info, boot from a cold boot, which does not boot into ALARM (it would suggest that interrupting the boot process and issuing the usb commands before boot has caused the HDD to disappear?):

Any advice?

WarheadsSE, you've been a great help so far... What would you suggest next?

[WarheadsSE]

My apologies, but for the moment I am scratching my head on this.

[LavaChild]

I know it's a serious problem when the Guru is stumped too! Not sure I've got much chance myself, in this case... In the meantime please do post an update if you have any ideas - Thank you!

[regder]

Just so you know, you're not alone! I have the same problem booting into a usb flash drive. Software restart goes into Pogoplug, hardware restart goes into Alarm.

Haven't had time to delve into it though
