Re: Question to usbdevs and dmesg
Hi! There is also sysutils/usbutil which provides usbgen package With that you could get the USB descriptors with something like: doas usbgen -D -v -f /dev/ugen1 on OpenBSD. However AFAICT it works with generic ugen devices. I don't know how to debug for example a USB mass media device. That being said, I have missed many times non-existing verbosity level for usbdevs which would dump at least device descriptor. Would this be desirable enhancement?

Ben Eater has a pretty good video on YouTube covering USB device discovery: https://www.youtube.com/watch?v=N0O5Uwc3C0o The bit about retrieving descriptors from the device is about 16 minutes in. -ken
Question to usbdevs and dmesg
Hi list, I've attached an XBOX 360 controller to my system. The controller gets detected as: usbdev: addr 02: 045e:028e \M-)Microsoft Corporation, Controller dmesg: uhidev1 at uhub1 port 1 configuration 1 interface 0 "\M-)Microsoft Corporation Controller" rev 2.00/1.14 addr 2 ugen1 at uhub1 port 1 configuration 1 "\M-)Microsoft Corporation Controller" rev 2.00/1.14 addr 2 Do you have an idea why the controller is detected as "\M-)Microsoft Corporation, Controller" and not as "XBOX 360 Controller" as it is defined in /usr/src/sys/dev/usb/usbdevs "vendor MICROSOFT 0x045e Microsoft" "product MICROSOFT XBOX360_CONTROLLER 0x028e XBOX 360 Controller" Thanks, Sven
