uh, cant sum of u read?

Hi! Sorry that I haven't been around for all this period; I really don't have time to play with this again until maybe mid September :( Did you make sure you have ID and GND pins soldered together in your Micro USB cable? From my memory, both the soldering and connecting external power source...

@4silvertooth: You can get a PC instead. They also have bigger screens to help you read more easily.

Hi, I did a bit more testing and figured out why it didn't work for me right from the start, and most likely why it doesn't work for you. Here are the exact steps one needs to follow to make the hardware act as USB host: 1. Turn off your phone (reboot doesn't work.) 2. Turn on your phone with...

I actually got a micro-B to mini-B adapter with all 5 lines connected, so I can cut the cable at any place to solder the ID and GND lines. Please do let me know when you get it working (or not...:) mine seems to work from time to time now) The charger burned when I was using it to power the USB...

Oh no, it's in the newer post :) If you have the time, could you also try to measure the following with that kernel installed: 1) voltage between VCC and GND when nothing is connected 2) voltage between D- and GND and the voltage between D+ and GND when only a charger is connected 3)...

Oops, I just noticed the build I uploaded doesn't work for me either; I changed some configuration and assumed it was harmless. They are updated now, sorry for the blunder :o

More updates. I'm using the LG kernel source LGP500(Thunder)_Android_Froyo_v10r.zip which is based on linux 2.6.32.9, with stock 2.2.2 system. Attached are the boot image, kernel zImage, and kernel config I used. You should be able to at least see some dmesg output this time. Sorry if it's not...

Some updates here! I took the plunge and got the Optimus One anyway :o The good news is that the LG v10r kernel source seems to have the USB host driver for msm7x27; it is just not compiled into the official kernels. I compiled a kernel with usbcore, ehci-hcd, usb-storage and usbhid built in...

Thanks, so it looks like it doesn't "just work". I can't be of much help just yet since I don't have the phone, but I think if you see nothing in dmesg, then first you have to rebuild the kernel with USB host support, using maybe the driver in ehci-msm7201_Blade.tbz in your second link.

Thanks! By being unutilised do you mean it's hardware related or it's "just" a software issue? I'll probably give it a try if can be enabled with a proper driver.

I'm looking for an Android phone that supports USB host mode. The Optimus One looks like a great phone but I can't seem to find anywhere whether USB host mode can be enabled for this phone. I'll have a separate power source for the USB devices, so the phone doesn't need to supply power in USB...

Don't be so quick to attack people, especially if you clearly don't know what you're talking about. Again, there is a possibility that FOTA just doesn't have the ability to mount SD cards, in that case "booting" from SD using FOTA would never work and you have to put the kernel in internal memory.

Take it easy buddy. I think omarittu94's intention is to help work out the easiest solution here. I know we were pointing out the obvious, but just in case. Since the phone doesn't need a SD card to boot, I think it's perfectly logical that the bootloader doesn't mount the SD card at all. Of...

Hi, I'm confused too. I'm only basing this on my experiences with PCs, but isn't it possible to just put the linux kernel and initrd in the media partition, and then mount the SD card from the linux kernel?
