Hi Kees, Thanks for your answer.
Do you mean few lines to configure in user mode the vbus as a wake-up source? I hope so. I had already checked pm.c in the past, but without finding any hint for user mode coding. Might I ask some additional suggestion to achieve this configuration without rebuilding the kernel?

It generally should be possible to configure the vbus as a wake-up source. Have a look at /mach-s3c2410/pm.c As some previous similar devices supported the wake-up on external power is probably will take only a few lines of code. buspower is used by the battery driver, the usbhost /device switching code and probably also by the navigation software.

The TomTom GO Buspower monitor driver might not be responsible for booting the device when powered on. Besides, it is loaded by the 9.4x kernel, in fact: cat /sys/devices/platform/tomtomgo-buspower/vbus returns 1 when the USB is powered and 0 when it is not powered. _____ Da: Amacri [mailto:ama...@tiscali.it] Inviato: lunedì 27 febbraio 2012 23.46 A: 'opentom@lists.gnumonks.org' Oggetto: How to start the "TomTom GO Buspower monitor" Hi, I am noticing that some TomTom firmware (like the latest 9.400 one) does not provide the capability to resume the device when its power-supply is witched on. After a short check to the GPL code provided at www.tomtom.com/gpl, I noticed the existence of the buspower.c driver module, that maybe version 9.400 does not load and that I guess is responsible for managing power supply events. Does anybody know how it can be manually loaded/activated through a Bluetooth tty connection to the device? Thanks Regards Amacri
