here's a framebuffer graphics demo (this has no practical purpose and I can't prove I'm not just like, playing a youtube video or something)

Thanks for the support!

If you set the bLength field of an interface or endpoint descriptor to zero, the parser will get stuck in an endless loop.
This causes the entire console to freeze when encountering a malformed configuration. Also not a big issue, but this was one of the things which lead me to discovering UDPIH :P

When reading multiple configurations, UHS doesn't change the size of the next configuration to be read.
So the initial read of the next configuration ends up being the full size of the previous configuration.
In practice this also isn't an issue, the device will simply respond with a short packet.

wIndex contains the Language ID for string descriptors.
This causes UHS to retrieve the first configuration multiple times if the device has multiple configurations.
In practice this is not a big issue though, most devices only have a single configuration and UHS will only use the first one anyway.

A USB device can have multiple configurations, which are retrieved using the GET_DESCRIPTOR request.
The index of the descriptor to be retrieved is stored in the lower byte of the wValue field.
UHS keeps this field as 0 and uses the wIndex field instead to retrieve multiple configurations.

There's currently no audio support. To avoid the USB loader memory size restrictions, the .wad needs to be compressed and then uncompressed to external memory on boot.
However, it's possible to load the shareware version of Doom entirely from USB, without modifying the Alarmo.
