Re: [Bluez-devel] How to confirm if a device has DFU support (dfutool)?

Hi everyone,
The previous issue I reported back about "dfutool" not capable of
backing up the firmware for a USB Bluetooth dongle (see below) is
solved.

It seems "dfutool" doesn't like VMware (v5.5.X). The native VMware USB
port emulation (or USB pass through) interferes with the raw USB
access required by dfutool. From a native OS (without any
virtualization SW) everything works as expected.

Cheers,
