Hi,

Looking at the code, "isoc" is only available when CONFIG_BT_HCIUSB_SCO is
enabled, which wasn't my case. AFAICT it's used for disabling SCO protocol at
runtime in the code, but just to make absolutely sure I rebuilt the module with
SCO support enabled, tried various values for isoc=, none changed anything. 

tried with "reset=1", didn't change anything either

FWIW, it's almost impossible to debug with CONFIG_BT_HCIUSB_DEBUG force set on,
for the machine is so slowed down that the timeouts would actually be
meaningful. Maybe this is why this config option isn't available from the config
menu ;)

Thanks for your help
