Kees Jongenburger wrote: On a side note I followed the HowTo EASILY Boot From MMC card and I now have boot from usb disk should that work with the same patch? In theory yes but you need to have correct modules and root device name set for the bootmenu item in bootmenu.conf, it won't work out of box. linuxrc script in initfs on N800 doesn't have any special suppport for this (n770 one has so there is 'usb' root device). But it should still work if the device automatically switches itself to host mode and detects usb device correctly. Maybe there can be also timing problem if you set usb as default boot device and skip the menu. Anyway, if you make it working, let me know your bootmenu.conf settings so I can add it to the n800 bootmenu.conf example configuration. Also if you need to set host mode by hand on boot it can be solved too in bootmenu.sh (see how poweroff is done). I'd like to try it too but don't have cable yet. I was thinking about building short usb female to female adapter so it could work together with normal mini-usb cable. Slight disadvantage is that probably that fifth pin for host mode autodetection doesn't have wire in the cable so I cannot shortcut it in the short adapter I want to build = software switching must be used.

Also the alternative is one of gender changers (example here http://usbfirewire.com/uconverters.html) The female to female can be used with two cables. There is also A Female to B Male which could be used with one cable (i.e you can attach digital camera with its own cable and this adapter only). Also this one can be modified to shortcut that fifth pin. But maybe this one can be too heavy and put more pressure on n800 usb connector.

Re: N800 experimental host mode patches available
Ok, now that I have loaded g_file_storage it looks much better but it still does not work for me. I use a powered usb hub, connected the upstream port to N800 and connected a usb keyboard to one of the downstream ports in the usb hub. I got a bunch of device not accepting address 11, error -71 messages in dmesg and the keyboard is unusable. When I connected my phone (mass storage mode) to the usb hub, the n800 froze and then rebooted. Marcell - Original Message From: Tony Lindgren [EMAIL PROTECTED] [...] Sounds like it should work based on what you described above. Do you have a powered hub connected?

Just for the record: I got the host mode working with a usb keyboard connected to the N800 through a powered usb hub.

Re: N800 experimental host mode patches available
Hi, I tried the usb host mode on my N800, but I did not get it working. Here's what I did: - In scratchbox SDK_ARMEL I downloaded the kernel-source-rx-34_2.6.18-osso40 sources, - Applied the patches-tusb-n800-2007-05-04.tar.gz patch set from muru.com (it did apply cleanly) - make n800_defconfig - make zImage - flasher -f -k -R /scratchbox/users/username/home/username/kernel-source-rx-34/arch/arm/boot/zImage - echo host /sys/devices/platform/musb_hdrc/mode I executed the last command twice and in dmesg there was a line saying that it is already in host mode, so I assumed that all is well now. However no matter what I connected to the USB port no message appeared in dmesg or in /sys/bus/usb/devices I used a male mini-B - female A converter that was plugged into the n800 and the memory stick / externally powered usb hdd was connected to that.

Hi, * Andreas Hubel [EMAIL PROTECTED] [070420 14:56]: do you or somebody else here know if the 770 also has this host detection via the ID pin feature? I don't think it has, but you can try it out yourself and see if you get an interrupt. The handling would be in drivers/cbus/tahvo-usb.c. And why does the USB chip of the N800 don't need this 5V from external? I thougt it also need it, because there is only 3V and no 3 to 5V converter inside the device.
