Hello!
When I try to use my keyboard through a StarTech SV431USBDDM KVM switch,
OpenBSD ultimately reports a device problem on the keyboard and disables
the port. When I use my keyboard directly, it works just fine and
doesn't exhibit any of the same problems.
I fiddled around with the kernel code to try and get a better picture of
why this was happening. It seems that the KVM switch is doing something
to mess up the keyboard's responses. In particular, after it receives a
request for the vendor string, it gives strange and incorrect responses
for the next couple requests.
OpenBSD is asking vendor string and then product string, so what's
happening in that sequence is that the 2-byte length request is being
told the product string's length is 16 matching the vendor string
(rather than the actual 26). Then the 16-byte string request is told
that it's actually 26, but because a length of 16 was requested, it only
receives back the first 16 bytes.
After this, the device replies to the next request with a garbled
version of the keyboard string no matter what, which is unfortunate
because the next request OpenBSD will make is for a config descriptor,
and if it gets anything other than a config descriptor back, it fails.
To get a better picture of how it was behaving, I tried various
modifications to the kernel code, on top of enabling debugging and
adding more debugging output:
1. I tried asking for the product string before the vendor string. This
got back the correct product and vendor strings for the cache, but
ultimately still messed up the following config descriptor request in
the same way.
2. I tried making the string descriptor request repeat until it gets an
actlen that matches the bLength. This worked, but no matter what, it
failed to get the correct product string.
3. I tried making the config descriptor repeat until it gets the
bDescriptorType it's expecting. This worked, though of course the cached
product string is cut short (from "USB Keyboard" down to "USB Key" - the
same number of characters in the vendor string "CHICONY").
4. I sent a mail to the Tech board asking about this one (because even
beyond this issue, sending two requests instead of one seems needless
unless actually required). I tried changing how string descriptors are
requested, so that it skips requesting a length, and just tells the USB
device to use the full length of the struct as needed. This actually
worked fine and seems to solve the issue completely.
Also, I was curious how this switch is working on Windows, and it seems
Windows doesn't even bother getting its vendor string, only its product
string. It also works on Linux (I'm not too sure why, but it reports the
vendor as "Chicony Electronics Co." rather than "CHICONY" so I'm
guessing they're doing the same as Windows), and even my motherboard's
BIOS USB drivers can handle it, so although it's behaving oddly, it
seems OpenBSD is failing to handle its quirks.
If you want logs or any other information, just let me know! The below
dmesg is from an unmodified kernel to show its normal behavior. The KVM
switch is reported as a "Genesys Logic USB2.0 Hub" rev 2.00/32.98.
At the line "uhub2 detached" near the end, I tried resetting the KVM
switch, just to show that behavior as well.
