This still doesn't look right

Code:

[  318.296875] musb_g_ep0_irq 709: SETUP packet len 0 != 8 ?

[  318.296875] musb_stage0_irq 570: VBUS_ERROR in a_host (91, <VBusValid), retry #1, port1 00000503

[  318.867187] musb_stage0_irq 646: CONNECT (a_host) devctl 5d

Was the hub really powered (i.e. attached to 5V adapter)? Also just in case you may try to reboot after you have the vbus error before further experiments with powered hub. When I get back to home I'll dig out my usb audio adapters and post sample kernel log.

I had it plugged into the wall with the adapter as well as the usb plugged into the n810. And the light was on on the hub. Are you saying I shouldn't be getting those VBUS_ERROR's?

It would realy suck if I needed at different usb hub ....... I'll try it with a flash drive tonight and see if I can get at any of the data through the hub.

How's about plugging the same setup into a desktop Linux box and looking at the output for comparison purposes?

Thats a good suggestion and I have been thinking about doing it. Only problem is I dont have a linux desktop. I run the dreaded Vista 64 Ultimate. I've been thinking of throwing together a linux box tho. Perhaps I will do it tonight or tomorrow. I need to set one up to run homeautomation stuff anyway. I have so many computer components lying around it wouldn't be hard. I probably have like 2-3 decent computers in my house doing nothing, haha.

Should I just throw Ubuntu on it? Or should I grab something like a Debian package (isn't ubuntu based off debian?)

Again I'm a linux n00b so it my be more effort than its worth for me.

Distro's are up to you :)

I use Ubuntu personally, and yes Ubuntu is based of Debian. You cannot grab a debian package to install Debian :). You use them to install stuff in Debian/Ubuntu.

Yeah that was a poor choice of words. I was asking if you can install Debian? I didn't know if it was a base OS or not. Would it be better to install a basic debian OS considering thats what Maemo kinda sorta is or should I put Ubuntu on there and I'll have the same results?

The tablet doesn't care. Ubuntu is about as close to ITOS as Debian is.

I'd pick Debian over Ubuntu, personally, but not for IT-related reasons; I can't make a useful recommendation for you -- I prefer Slackware over either.

Yes. So far I've seen these errors only when tablet couldn't give enough power. Such device then didn't have enough juice to power itself on fully and communicate over USB. Powered hub fixed the problem. I've seen this with 2.5" hard drive in usb box, SDHC card reader and XBOX gamepad. Powered hub always fixed the problem, same hub with power disconnected had same problem.

When detected on linux PC check MaxPower parameter of your device in dmesg log. This tells how much power device needs.

You ought to be able to use one of those distro-on-a-CD jobs (what are they called? - liveCD?) just to do this one job, rather than having to build a new machine (though in the long term having a real Linux box will help you learn).

Yeah, I thought about using a LiveCD as well. I have been meaning to set up a linux box for a while now. This is as good as an excuse as I will probably get! Good suggestion tho. If I run short on time I may give it a go.

Can you lsusb with it attached?

(I wonder if something like usb_modeswitch is needed...)

Ok, here's the scoop. Looks like its a proper USB audio device after all:

If you have a spare box to dedicate to it that's great. The newest Ubuntu also has something called "wubi" which lets you install on an existing windows box without repartitioning. There's also the free vmware player if you want to run it in a virtual machine on windows.

I've used VMware player and have ubuntu on my vista box right now. But it doesnt seem towrk quite right in vmware player and since I am completely new to it I dont know how to get it running properly. I wanted to set up a linux box anyway, however, that "wubi" thing seems pretty neat. I have a bout 100 Gigs left on one of my drives so maybe ill give that a go!?!

I'll take that as a good sign. I think tht just means I dont have the right drivers than? And how do I point the n810 to start using that device as opposed to the other?

This whole things seems much harder than it should be. I wish i knew what thehell i was doing haha.

Not really. I realized that I could hook my n810 up to my car stereo system through the headphone jack and have been working on that ... Sounds good! I would still like to get the usb working tho. I'm currenty making a double din snap in custom dash for my car. I'll post some pics when im done.

Progress wise: I tried it with a powered usb hub and things just go crazy. I think i am going to hack or buy a real OTG cable (Instead of using USBcontrol) and then hope that some better USB support comes out in the near future (diablo?) while i am working on the dash of my car. If not I will get back to work on it.

I'm not really sure what you are trying to show me with this post? I understand that it is possible, which is pretty much all that link tells me. It doesnt link to any of the modules I need nor does it have a specific "how to" on what to do to get it set up. Could you clarify a little?
