<@whitequark> does anyone want to debug a horrible USB issue?
<@whitequark> <...> BULK IN URBs not finishing
<me> is this a ZLP issue?

As far as I can tell the sole decent use case for XMOS is USB audio (or maybe other audio). I have a DIY DSP thing running my speakers using an XMOS and it has better latency (0.25ms analog-to-analog, ish) than ~every high-end DSP box you can buy.
That's running 15 biquad EQ filters × 6 channels at 96kHz 32bit internal resolution (24bit codec), on two XMOS chips. Good luck getting that latency on a traditional DSP. But for anything else? Stay far, far, FAR away from XMOS.

In 2013 @0x111a and I designed a board that was essentially Glasgow (even the same 74LVC1T45 level translation), except with XMOS for lack of an open FPGA toolchain, and quickly came to the same assessment of the XMOS ecosystem.pic.twitter.com/eIiwtR8FBE

At least you weren't crazy enough to try to use that cursed dual-row QFN package.
