Can't flash firmware anymore, stuck on 1.0.9 #6
Description
After receiving my respeaker (without ESP) a couple of days ago I tested with the pre flashed usb firmware what was working as expected, after testing I flashed respeaker_lite_i2s_dfu_firmware_48k_v1.0.9.bin, which is also working fine on my raspberry.
Now I wanted to flash the usb firmware again, and it seems to be flashing correctly but it stuck on 1.0.9:
patrick [ Schreibtisch ] $ sudo dfu-util --verbose -R -e -a 1 -D respeaker_lite_usb_dfu_firmware_v2.0.7.bin

What I've noticed, it only takes ~3 seconds to flash this respeaker, flashing any other respeaker lite takes ~6 seconds.
I've tested a couple of different firmware versions (from this repo) but it does not change anything.
Any help appreciate, thanks.
