Re: [Announce] USB hostmode beta release
 

a reflashing can't alter the power that N900 can provide. It always should be 5V@200mA - only charging battery may improve behaviour in some niche cases.
Plugging in the peripheral after starting VBUS boost sometimes helps.
Honestly, I doubt 200mA ever can be enough to start up any but the smallest HDD, I suggest using a Y-cable and USB PSU, or a selfpowered hub for this

Re: [Announce] USB hostmode beta release
 

Thanks but i tried the same 2.5 HDD and the same USB Sticks with the exact same cables as before with no luck..Could it be Power Kernel's Voltage settings? Though I haven't change anything but the max. freq.

I also tried to connect after startung th VBUS but it keep saying "port 1 not enabled, trying reset again.... ... port 1 not reset yet, waiting 200ms" and it gives "port_wait_reset:err = -16"

Is there anything else i can try?

Re: [Announce] USB hostmode beta release
 

sorry but do I understand it right you OCd your device and now complain h-e-n doesn't work? Maybe even previously with a sane cpu clock and now massively OC'd?
Of course the chip internal interface from cpu to musb-core is susceptible to voltage and clock changes.

If you had a HDD working before, you were lucky.

I work for an electronics company, and we deliver 500mA and still have problems with most usb drives. (its all up to power)
I have similar issues, sometimes I have to restart the n900 and then it works better.
also I noticed using a powered hub improves stability. I guess thats because the hub handles device speeds, or whatever.


@joerg_rw: regarding my other problem I never stated its anyones fault, just asked for support.

Re: [Announce] USB hostmode beta release
 

Err, yes. So what? What did I say? How's c&p of apt-cache results making you talk about fault? Or was it my next post that said "probably only headers needed"?

:confused:

Re: [Announce] USB hostmode beta release
 

I didn't complain about anything, I was just saying that with the same settings as before (same max freq etc) flashing, everything worked pretty good!

And let's assume that with the USB HDD I was lucky..what about the USB sticks? They should be working..at least not giving me that "port" error..

Re: [Announce] USB hostmode beta release
 

Sorry maybe I offended you. Didnt mean that.

One quick question: did the power kernel get installed with the h-e-n or did I do that and just cant remember that I did it?

Re: [Announce] USB hostmode beta release
 

any update coming to the beta?

Re: [Announce] USB hostmode beta release
 

hi please help
what's the problm? after connecting the dvd-rom I go into the kernel messages and no calculations on the sr0.
I have a kernel power in 45, and additions MohammadAG to handle cd-rom
my kernel

[ 5162.718414] USB Mass Storage support registered.
[ 5162.721343] usb-storage: device found at 3

Thank you

Re: [Announce] USB hostmode beta release
 

I am using PowerKernel v46 multibooted with Nitdroid Ginderbread and the omap pr1.3 Kernel i installed the h-e-n software and bought the female to female converter...i am trying to connect a transcend 4gb flash drive with fat32 file system.
I run the device at high speed. nothing happens. some times when i open file manager it says no filesystem found(this is a rarity... most of the times nothing happens at all).
could someone suggest what might be going wrong?... any help will be appreciated...

EDIT: i also tried different speeds... nothing happens
