[Help Needed] Can't figre out why usb hub doesn't work

[winnetouch]

Hy.

I just made my GB0 almost working. There are only 2 issues I need to get arround. One that's the most frustrating is the USB hub. I used an unpowered usb hub (since the targus one in wermys guide is also not externaly powered). I soldered the male jack data cables to the coresponding usb pads on the pi. Also I wired the powere cables directly to the power strip (a homemade one on a perfboard not helders). The usb hub has only 2 ports. One goes to the teensy and the other to the USB breakout (where the GB link cable normaly sits). I wired the breakouts data cables to the hub, and the power lines to the power strip. But the hub doesn't work. Neither the teensy nor the breakout. When I wired the breakout data wires directly to the coresponding pads (still keeping the power wires on the power strip) on the Pi0 it worked fine.

So I'm guessing I'm wiring something wrong with the hub. Or did I just understand something wrong in Wermys guide?

Post pictures of the install and have you tried to twist the data lines?

I'll sketch up a diagram what i did. The project is riddled with wires because i used a tft screen and a powerboost alternative, so i had some extra wiring to and the project looks kind of messy.

No I've not tried tangling the data wires I'll try that next.

Here is how I connected the thing. I haven't found the time to try tangled wires yet because I need to find some longer wire I don't have handy at the moment.

EDIT: I tried twisting the wires while having the hub connected as diagram bellow. The pi turns on (the screen is white) but it never boots up from the SD card... Weird.

Anyone? I'm kind of torn between keep trying with the hubs I've already got or to just give up and get an externaly powered usb hub and do it that way (though I'm not that keen on that idea).

Perhaps you can give this a try:

going by your diagram above it looks like you have your input and output switched on the hub pi0 > hub on the input then your teensy and external port on the outputs of the hub.

Um... Maybe i labeled it wrong but i think i didn't. Isnfta usb considered an input device? Regardless... I used the correct set of cables. That part was the male usb jack that pluged in to usb. I just sliced it up and connected it to the ports as shown.

Also i think it's more of a power issue. The leds on my keyboard light up when i plug it in then immediately turn of. And the keyboard doesn't work. I'm suspecting it doesn't draw enough power or it's not grounded right.

after 2 days of pulling my hair out I gave up and ordered a powered usb hub. So I hope that one will work as it should. Now I just have to wait for it to arrive.
