-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Somebody in the thread at some point said: | Hi there, | I am thinking about trying switch the FR (running Debian) to USB host | mode, put in a USB hub and connect a external USB Disk, a keyboard, a | mouse and the USB charger that comes with the FR. Would that work, | that is, can the FR be charged while being in host mode so the battery | doesn't get drained at once by the external drive?
You can do it, but you need to be in logical host mode ~ - echo host > /sys/devices/platform/s3c2410-ohci/usb_mode but NOT electrically in host mode ~ - echo 0 > /sys/devices/platform/neo1973-pm-host.0/hostmode The reason is that part of the deal of being electrically in host mode disconnects the USB socket V+ from the PMU, that alone will defeat the possibility of charging no matter what else you do. Another side effect of not being electrically in host mode is you need to externally add 2 x 15K pulldown resistors, one on D+ and the other on D-, with that you should be able to have the external power, charging, and USB devices all at the same time. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkjpFCgACgkQOjLpvpq7dMp8UwCZAVTxn5Urd5iKJESzDFA/qJtA GboAnjB9Ob9BgBAVXiFuSPDyple4Jar6 =uTVf -----END PGP SIGNATURE----- _______________________________________________ Openmoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
