You have to connect a single stick with the Ultrmap software and you can then assign it as Stick 2 (product ID 0512). Then you can connect the other stick and it will id as Stick 1 (0511). So I presume it reprograms the NV memory it the stick to...

You are correct. If I only ever connect the sticks to the PC one at a time they both ID as 0511. Then when I connect both to the Teensy they both still ID as 0511. It's when you run their Ultramap software on the PC with both sticks plugged in...

Good point. It's been a long time since I made the panel up with both sticks in and I have certainly used the PC app with them. It certainly didn't come up with a Change ID option but could well have done it automatically. I need to reflash one...

My first thought was this so I powered the hub & sticks independently only taking the D+/- from the Teensy. Still got the same issue. I do have another pair of Ultrastik360's and a different hub somewhere just need to find it. May be just the hub...

The hub is just a generic chineese USB 2 one and the joysticks are 2 x Ultimarc Ultrastik 360's. Joystick link It was failing to boot cleanly about 50% of the time, the delay would take around 3-4 seconds. The reset must have been caused by...

Well a bit more reading of the code and I realised I needed to check the "haltedpipe" pointer. It was NULL even though the next portion of code relied on it being a valid pointer. I then added a check for "haltedpipe" being NULL and bypassed the...

ok. I have been adding extra debug lines to "void USBHost::followup_Error(void)" in ehci.cpp It seems the "While (p)" at line 927 never exits even though p gets sets to NULL ERROR Followup remove from followup list not halted 20005180...

I didn't make this clear in the last post, but it does boot on occasions fine without the reset. I have turned on USB Debug Msgs and here is the later stages of the log which shows the error msgs when it goes wrong and hangs for a reset. The...

I am updating my Ultragun Arcade controller to use a Teensy 4.1 instead of an Arduino Due with USB Host board. After much head scratching I now have both joysticks working fine except for startup which seems to reset the Teensy after the first...
