colorhug-flash failure

[Michał Nazarewicz]

I’m trying to update firmware on my ColorHug, so I connect the device
and get the following in dmesg:

[28159.983482] usb 3-1: new full-speed USB device number 12 using uhci_hcd
[28160.179040] usb 3-1: New USB device found, idVendor=04d8,
idProduct=f8da, bcdDevice= 0.02
[28160.179046] usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[28160.179050] usb 3-1: Product: ColorHug
[28160.179053] usb 3-1: Manufacturer: Hughski Ltd.
[28160.185608] hid-generic 0003:04D8:F8DA.0011: hiddev1,hidraw4: USB
HID v1.11 Device [Hughski Ltd. ColorHug] on usb-0000:00:1a.2-1/input0

I then run colorhug-flash (version 0.2.8, packaged with Debian) which
detects that a new firmware is available:

$ sudo colorhug-flash
1.2.3 compared to 1.2.0 = newer
1.2.2 compared to 1.2.0 = newer
1.2.1 compared to 1.2.0 = newer
1.1.8 compared to 1.2.0 = older

So I hit ‘Update’ and the tool does something for a bit but then spits
out the following two errors:

usb:00:01: Invalid read: retval=0x0b [Unknown command for bootloader]
cmd=0x0b [get-serial-number] (expected 0xb [get-serial-number]) len=2
(expected 6 or 64)
usb:00:01: USB error on device 04d8:f8da : No such device (it may have
been disconnected) [-4]

Anyone has an idea what’s wrong?

Here’s some more debug info:

Could you try with fwupdmgr? That's been the supported update
mechanism for some time.
