Subject: [Bluez-devel] How to completely reset a dongle from software?

Hello,

Is there a way to perform a full reset of a USB dongle without
unplugging it, but having the very same effects than if it was
physically unplugged and plugged back again?

I encountered some firmware jams with my dongles, and the only solution
to get them back to work again was to etither unplug them or to reboot
the machine. This is quite annoying for some applications where system
has to be up as much as possible, and has to self-recover unattented if
something goes wrong.

Very interesting. Unfortunately, the dongles I'm working with at the
moment are all broadcom-based. Does the same tool/functionnality exist
for this brand of devices?

if it is a csr chip, you can enable bccmd in bluez-utils and use it to reset
the chip. It might take two attempts to actually reset.
