Hi misc@, I've spent a couple evenings working to port trezord-go, and I'm hoping someone with USB experience can give me a few pointers based on what I've found so far.
For background: Trezors are a line of hardware crypto-currency wallets. The idea behind them is to keep private keys for crypto-currencies off of your computer / phone and on a "more secure" device. Trezord-go allows the Trezor application, which runs in the browser, to talk to Trezor wallets. Basically, it is a local web server that sits between a web application (at <https://wallet.trezor.io/>) and USB devices. The project is at <https://github.com/trezor/trezord-go>.
Trezord-go uses two libraries for USB communication: HIDAPI <https://github.com/signal11/hidapi> and libusb-1.0 <https://libusb.info/>. HIDAPI has no support for OpenBSD, but libusb does. Fortunately, trezord-go doesn't depend on HIDAPI and can use libusb alone, and libusb is in ports. (Great!)
One wrinkle is that trezord-go uses a vendored and patched version of libusb, apparently based on 1.0.21, and the OpenBSD backend (libusb/os/openbsd_usb.c) was stripped in the process. We can tweak the build process to use the system's libusb instead and retain core functionality. This was the approach taken for the FreeBSD port (using FreeBSD's own libusb implementation). I've taken the same approach so far.
Trezors are HID class devices and have uhidev and uhid drivers attached. Example:
> uhidev4 at uhub0 port 2 configuration 1 interface 0 "SatoshiLabs TREZOR" rev 2.00/1.00 addr 8
> uhidev4: iclass 3/0
> uhid3 at uhidev4: input=64, output=64, feature=0
> uhidev5 at uhub0 port 2 configuration 1 interface 1 "SatoshiLabs TREZOR" rev 2.00/1.00 addr 8
> uhidev5: iclass 3/0
> uhid4 at uhidev5: input=64, output=64, feature=0
But libusb on OpenBSD only supports ugen devices. So I added the Trezor to usb_quirks, forcing the ugen driver and rebuilt my kernel.
dev/usb/usbdevs.h:
> #define USB_VENDOR_SATOSHILABS 0x534c /* SatoshiLabs */
> #define USB_PRODUCT_TREZOR 0x0001 /* TREZOR */
dev/usb/usb_quirks.c:
> { USB_VENDOR_SATOSHILABS, USB_PRODUCT_TREZOR, ANY, { UQ_BAD_HID }},
And ugen attaches as expected:
> ugen0 at uhub1 port 1 "SatoshiLabs TREZOR" rev 2.00/1.00 addr 7
At this point, the Trezor application recognizes and can load some information from the wallet, but it seems to stall right before you would typically enter your PIN.
I don't have any experience debugging USB devices, but (after double-checking permission issues) I jumped into the libusb codebase. Trezord-go uses libusb_interrupt_transfer() to read and write from the device. My first concern is that the ugen man page states: "The interrupt transfer mode can only be in." Using lsusb from the usbutils port, it looks like the Trezor endpoints only support interrupt transfers (two interfaces, four endpoints):
> Endpoint Descriptor:
> [...]
> bEndpointAddress 0x81 EP 1 IN
> bmAttributes 3
> Transfer Type Interrupt
> [...]
> Endpoint Descriptor:
> [...]
> bEndpointAddress 0x01 EP 1 OUT
> bmAttributes 3
> Transfer Type Interrupt
> [...]
> Endpoint Descriptor:
> [...]
> bEndpointAddress 0x83 EP 3 IN
> bmAttributes 3
> Transfer Type Interrupt
> [...]
> Endpoint Descriptor:
> [...]
> bEndpointAddress 0x03 EP 3 OUT
> bmAttributes 3
> Transfer Type Interrupt
However, my read of OpenBSD backend for libusb is that interrupt transfers out are ok / anticipated (they only aren't supported in conjunction with the LIBUSB_ADD_ZERO_FLAG_PACKET flag, which isn't set in this case).
After enabling debug output on libusb (rebuilding the port), it further looks like the calls to write from the backend are succeeding. So at this point I either don't understand the man page or the libusb codebase. :)

The "CHB" debug lines are my additions to libusb's debugging output. The call to write happens between the two _sync_gen_transfer lines, and it returns 64 (bytes written).
My second concern is that it appears a call to _sync_gen_transfer() doesn't return, which happens when the application stalls (apparently for input from the device).

We don't get any more debug output from libusb after this point. Trezord-go does it's own logging, and it looks like again there is a read call that doesn't return:
> [...]

(The Trezord-go log is read from bottom to top.)
I've included lsusb and dmesg output below. I've also captured USB traffic ('tcpdump -s 512 -w trezord-go.pcap -i usb0') and filtered for the device using Wireshark ('usb.addr matches "0.7"'). The capture file is at <www.colinhb.com/tmp/trezord-go.pcap>. A trezord-go log is at <www.colinhb.com/tmp/trezord-go-log.gz>.
As I mentioned, I'm looking for any pointers from people with more experience with USB and the USB subsystem - I only have the barest understanding of their implementation. Hopefully there are some signs of common or known OpenBSD issues.
Finally, my working trezord-go repo is on gitlab at <https://gitlab.com/colinhb/trezord-go/tree/openbsd> if anyone wants to take a look. Thanks in advance for any help. Also if any developers are interested in these devices, I'd be happy to buy one or two of them and have them shipped. Just email me off list with your name and address.
