Re: N800 USB Host Mode Experiment
The N800 will just shut off the 100mA-limited supply and stop working in host mode. You'll need to reboot to fix it. Nothing will be permanently damaged.

Re: N800 USB Host Mode Experiment
My understanding is the he is making a USB A-female to A-female adapter - this only would have 4 pins - 5V, Ground, D+, D-
He will need to do the host mode switching manually.

Re: N800 USB Host Mode Experiment
Whoa, don't do that! You just flipped all the wires... including connecting 5V and Ground in reverse (so -5V to your device). You should wire pin 1 to 1, 2 to 2, 3 to 3, 4 to 4.

Re: N800 USB Host Mode Experiment
Probably it's claiming that is what it might need if you plugged in all of the cards and they were all drawing max power. You're probably safe overriding this ... you might need to change a constant...

Re: N800 USB Host Mode Experiment
So, it looks to me that black should be connected to blue, the rest map 1-1, and the orange wire is the extra sense wire that needs to be connected to something (ground?) to tell the device to go...

Re: N800 USB Host Mode Experiment
Hey, for debugging, try:
dmesg -c
in console. You should be able to see what's going on exactly. It may be you need a kernel module for the device you're using. I haven't had any luck with...

Re: N800 USB Host Mode Experiment
I have not tried that specific cable with a hub (I don't have any hubs with a mini-B downstream connector). I have, however, used a similar cable (mini-B to A-female to standard USB cable) to...

I bought some of these cables:

They work fine for my full-speed mini-B application.

CBUS_TAHVO_USB=y
CONFIG_USB=y
CONFIG_USB_OTG=y
CONFIG_MUSB_HDRC=y
CONFIG_MUSB_HDRC_HCD=y
Also, added some...

Re: N800 USB Host Mode Experiment
Probably not the smartest way to do it, but I was able to get the kernel to compile by adding an argument of NULL to musb_host.c line 286's call to usb_hcd_giveback_urb'...
