I'm using nanopi-neo2_FriendlyCore-Xenial_4.14.0_20171208 kernel.
OTG mass storage works, the device is visible on a Windows PC and functional.
Then I try to configure an HID gadget:
Windows PC recognizes an HID device, but says that the device cannot start (Code 10), STATUS_DEVICE_DATA_ERROR.
USB capture shows no errors, but there are only 12 packets:
dmesg:
lsmod:
Any help would be appreciated.
