Thank you, that's valuable info!
I've sniffed my USB communication while running PicoPix Viewer.exe and got
a large UsbSnoop.log file. The important lines of log file are:
[557488 ms] >>> URB 1249 going down >>>
-- URB_FUNCTION_BULK_OR_INTERRUPT_TRANSFER:
PipeHandle = f9da5bcc [endpoint 0x00000001]
TransferFlags = 00000000 (USBD_TRANSFER_DIRECTION_OUT,
~USBD_SHORT_TRANSFER_OK)
TransferBufferLength = 0000001f
TransferBuffer = f9e4cb28
TransferBufferMDL = 00000000
00000000: 55 53 42 43 08 90 d8 f9 00 00 00 00 00 00 0c ff
00000010: 02 00 00 00 00 00 00 00 00 00 00 00 00 00 00
UrbLink = 00000000
That is second last URB_FUNCTION_BULK_OR_INTERRUPT_TRANSFER in "going
down" mode. So my /etc/usb_modeswitch.conf file is (also attached):
DisableSwitching=0
EnableLogging=1
DefaultVendor = 0x1de1
DefaultProduct = 0x1101
MessageEndpoint = 0x01
MessageContent =
"555342430890d8f90000000000000cff020000000000000000000000000000"
After running:
sudo usb_modeswitch -c /etc/usb_modeswitch.conf
My PicoProjector went black, and lsusb showed:

But I didn't get any /dev/fb* files, and make check from libdlo-0.1.2
