@whitequark I see, that's understandable. Still awsome, I'll definately get one
@whitequark That's very exciting, looking forward to it :3 ! I know it's a long shot, but I was wandering if usb3 SS could be possible (maybe with the new chips from wch or the FX3) instead of the usb2 interface.
confession: for several years i had assumed, unquestioningly, that "SMP Minecraft" is for "symmetric multiplayer"

Hay! I'm done with beautiful player for @phosh written in @vala_lang

@whitequark re: USB
I've tested it again and I can repro it with just two fx2lafw, this is the output: https://pastebin.com/U4XTrBS3 . Indeed they appear on the same HS bus even tho they are connected to different usb 3 ports. This also happens on other controllers I've tested

@whitequark I'll retest it tomorrow and send it. But yeah, lsusb -t was showing a usb 2 hub created under the usb 3 one. and all usb 2 devices where under that (even tho they were phyisically connected to two different usb 3 ports, on the same controller)
@whitequark oh yeah I get it, no worries! thank so much for the insights!
@whitequark re: USB. I had those issues while connecting more than two fx2lafw directly to my motherboard's usb 3 ports, and I solved them buy buying another usb 3 controller that also caps out at two. Never figured out why tho
@whitequark mhh circuits like that would only allow reading the bus, did I understand correctly? I guess its fine tho, I can connect the gpios that need to be read/written directly and the rest via the latch and that would be more than enough for most 8 bit stuff.

@whitequark I'd love it for retro stuff! On that note, when I think about retro interfaces, a lot of them are parallel busses (think game cartridges, PATA, and so on) that require more than 16 pins to operate, so having a well designed syncronization system to use two(or more?) glasgows in conjunction would be a (literal)game changer :p . I've read that's a supported use case, but I haven't found code/examples on how it works.

For example, would I be able to use sync two glasgows and have them send parralel bus/logical analyzer data over (ofc assuming I have enogh usb2 controllers to support that troughput) ?
