Hi,
I just received Sparkfun QuickLogic board. After connecting it via
USB, I found following device:
# usbconfig -d ugen0.5 dump_all_desc
ugen0.5: <vendor 0x1d50 product 0x6141> at usbus0, cfg=255 md=HOST
spd=FULL (12Mbps) pwr=ON (100mA)
bLength = 0x0012
bDescriptorType = 0x0001
bcdUSB = 0x0200
bDeviceClass = 0x0002 <Communication device>
bDeviceSubClass = 0x0000
bDeviceProtocol = 0x0000
bMaxPacketSize0 = 0x0020
idVendor = 0x1d50
idProduct = 0x6141
bcdDevice = 0x0000
iManufacturer = 0x0000 <no string>
iProduct = 0x0000 <no string>
iSerialNumber = 0x0000 <no string>
bNumConfigurations = 0x0001
Searching for VID and PID did not get me anything. Trying any of our
USB serial driver did not create any device. How can I connect to
this device? It should be some serial port because that's what
Sparkfun page says... Any hint?
Regards,
Milan
N. B. I was able to connect to this device using my Mac:
# cu -l /dev/tty.usbmodem1411
Connected.

Hi!
Did you try to dump the configuration descriptor?
Maybe umodemX can handle it ...
I forgot to write I have all available serial drivers loaded, i.e. in
kldstat output
54 1 0xffffffff81ae9000 23a0 umodem.ko
55 7 0xffffffff81aec000 4d10 ucom.ko
56 1 0xffffffff81af1000 22a0 uchcom.ko
57 1 0xffffffff81af4000 2200 ucycom.ko
58 1 0xffffffff81af7000 21e0 umoscom.ko
59 1 0xffffffff81afa000 2aa0 uplcom.ko
60 1 0xffffffff81afd000 32e0 uslcom.ko
61 1 0xffffffff81b01000 2260 uvscom.ko
This is from a 13.1-STABLE system.
What you mean by configuration descriptor? Is it this:
# usbconfig -d ugen0.5 dump_all_config_desc
ugen0.5: <vendor 0x1d50 product 0x6141> at usbus0, cfg=255 md=HOST spd=FULL
(12Mbps) pwr=ON (100mA)
# usbconfig -d ugen0.5 dump_curr_config_desc
ugen0.5: <vendor 0x1d50 product 0x6141> at usbus0, cfg=255 md=HOST spd=FULL
(12Mbps) pwr=ON (100mA)
There is just this, nothing more. Could some usbdump help to identify
the issue? I have no experience with this, also no idea how an initial
device discovery could be catch with usbdump :(

Hi,
cfg=255 means there is an error to set the configuration index.
Try to use usbconfig to set config index 0 again? Maybe it just works?
