Caught Halfway Through Sprite's Usb Mod!

Hi guys,

I finally bit the bullet and followed Sprite's Mod to add a USB port and tap the 5V internally. Guess what? During my test with long leads, it all works!

But now that I have trimmed back the wires, hot glued, and reconnected most of it, I checked back to sprite_tm's site and the images have dissappeared! Especially the simple schematic.

If I check the image URL's directly from his site (they were hosted from his university account), I get a 403 Forbidden message.

In desperation I tried a google image search to his domain to try and locate at least a thumbnail. Couldn't find the GP2x related images.

Then I tried the wayback machine. No go.

Does anyone have a mirror copy of spritesmod.com GP2x USB instructions, or just the schematic?

I can't believe the images disappeared just as I was finalising it all. :(

I am totally out of options and I have no contact information for sprite_tm. Any help would be greatly appreciated.

I'm at work at the moment and the site appears to be dead. I presumed it was a knock on from yesterday, but it might be the network. I'll try a proxy browser to get to it and get in touch with him.

In the meantime, anyone got a copy on their PC?

Ok, I proxy browsed to it and left a message. Thanks for the confirmation there. I'll see how it goes.
 
I might have the images somewhere, Ill check later this day.

BTW, I did this mod aswell, It worked perfectly, but when I played longer than a hour or so my USB port got really hot, and eventually my GP2X fried..
I'm sure I followed the schematics perfectly, I hot-glued all the solder points to prevent leaking, but still this happened..
So I hope for others I did something wrong..
 
Sounds like your USB device was pulling too much current for too long. Maybe a hot joint (read: bad electrical connection) exacerbated the problem. What were the circumstances?
 
Thanks, Gavie. Yes I'd be interested to know the circumstances as well, as this is not the first time I have heard it mentioned that the mod fried a console. Unless you once mentioned it elsewhere.

I used a 100uf instead of 68uf cap. Never seen a standard 68uf cap and noone can sell it to me. My electronics experience is very minimal and I don't know if a higher cap value will smooth out the current more. Perhaps it just stores and releases charges slower.
 
Yeah I might have mentioned it before in another topic, but I have read more people having troubles with this mod..
The circumstances, well the solder points at the backside of the connector are VERY hard to solder, the contacts are very small and the wires break off easily.. Furthermore I haven't experienced any problems during the process, but if this doesn't happen to others, there must have been some kind of mysterious leak or something :p..

I have found the pictures, including the *well drawn* schematic and pictures of an other guy that posted his result in the comments..

EDIT: File has been deleted, if anyone else needs it, just PM me
 
Thank you so much for the archive. Sprite_tm did get the images back up, however, it's still not working, and I'm so sure I have checked everything.

Once the images came back, I noticed I had gotten USB+ and USB- around the wrong way, so I corrected that. So I am concerned that my power on tests with the wires switched around might have caused some damage.

I do a dmesg in the sterm without any devices attached and there are no
messages. I go to Settings and just switch on the USB Host function.

dmesg then gives:

If I go back to the settings and enable the HID device, dmesg gives the
additional:

usb.c: registered new driver hiddev
usb.c: registered new driver hid
hid-core.c: v1.8.1 Andreas Gal, Voljtech Pavlik <vojtech@suse.cz>
hid-core.c: USB HID support drivers
mice: PS/2 mouse device common for all mice

So there are good messages there and bad ones. I sent this output to sprite_tm so it will be interesting to see what he says.

As a way to test the regular USB (non-host mode) port, I connected this to my PC and turned on USB, and the gp2x acts like a drive. So my gp2x hasn't blown it's USB hardware thankfully.
 
Hello guys! Sausage I too have been having trouble with the usb mod. I have looked at the messages I get when enabling usb host on my gp2x F200 and it is almost identical to your output. Ive made a usb cable but am getting errors when I plug in a usb device.

hub.c: new USB device <NULL>-1, assigned address 6
usb.c: USB device not accepting new address=6 (error=-110)


Sausage what kind of output are you getting when you plug in a device? The same error?

I seem to get the same output when plugging in usb mice and flash drive.


Thanks for any advice!
 
Well I got the error when activating the module. So plugging in devices just clouded the errors. But we have the same problem for sure. The author of the article was stumped.

I removed all wiring and used a PCM cleaner and there is no change now.

I think something in the USB circuitry popped or some other component died. The rest of the unit is fine.

I'm dissapointed that although USB Host Mode is supposed to be available, in reality, it's not without modification and risk. Perhaps the next version will be better. I wanted an all round cheap unit that could play games, music and occasionally used to write simple documents with an external usb keyboard (ie Alphagrip AG-5).
 
Ok after some tweaking and double checking I found that I had used a 33k resistor instead of a 33 ohm resistor on the usb filter! :eek: Also the errors that I was getting on when I enabled usbhost were normal, if you look at the gp2x usb host wiki ( http://wiki.gp2x.org/wiki/USB_Host ) and look at his output he has the same errors.

And guess what! when I plug in my usb flash drive I get this output from dmesg:

Sausage I hope your able to fix what ever is wrong with your gp2x, I kind of doubt that its usb hardware has fried in some way.. by the way, what model and firmware do you have?

I have the gp2x f200( b ) firmware 4.0 B)

Later dudes!
