I have no clue hwy it wasn't working before. I ran lsusb three times - (1) nothing plugged in, (2) only mac multiport adapter, (3) ISP programmer plugged in to adapter - and it found the usbtiny!!

I also found this brew package that makes a lsusb command for mac - I installed and it appears to give the same info as the system report, but the package is about 5 years old and since I think the issue lies with the newest macbook changes (or else previous fabclass documentation would work) I won't rely too heavily on this replacement. To see all USB devices plugged in: apple > About this Mac > Systen report > Hardware > USB -everything should be listed. Now I need the same thing to happen on my macbook.įirst off, macOS doesn't have a simple lsusb command like ubuntu. When I plug in the programmer (from week 2) to the USB 3.0 hub on my ubuntu machine and run lsusb the device appears as 'Multiple Vendors USBtiny'. Starting with the macbook problem so maybe I can continue workingn on future programming issues from the comfort and warmth of my own home. I know that it's not an issue with the USB 2.0 vs USB 3.0 adapter because I'm able to find the programmer with a USB 3.0 hub on the ubuntu machine. I've been side stepping the issue by doing all the embedded programming on my CBA ubuntu desktop, but I'd like to be able to program in the lab and remotely on my laptop. I've tried multiple different USB-C to USB adapters - making sure to account for the timer differences in USB 2.0 and USB 3.0, but in all cases my macbook doesn't recognize the programmer. I have a 2018 macbook Air, so it only has USB-C ports. basically, talking over serial was a one-way communication.Īlso, from week 2 still can't figure out how to program the circuits from my laptop. I could read signal from the device on my computer but couldn't get signal to the device (or couldn't get the device to return signal that it received from the computer?). It will keep retrying.Back in week 4 I designed a board that mostly worked. USBF: 10422.789 The IOUSBFamily is having trouble enumerating a USB device that has been plugged in. 84 The IOUSBFamily was not able to enumerate a device. USBF: 10416.549 AppleUSBEHCI::Found a transaction which hasn't moved in 5 seconds on bus 0xfd, timing out! (Addr: 0, EP: 0) This is coming from the dmesg, not sure if it is related to the device: USBF: 10410.547 AppleUSBEHCI::Found a transaction which hasn't moved in 5 seconds on bus 0xfd, timing out! (Addr: 0, EP: 0) dev/tty.Bluetooth-Modem /dev/tty.Bluetooth-PDA-Sync While I can connect to the device using modprobe usbserial on Linux, how can I do it on Mac? It only gives me the following: $ ls /dev/tty.* I have an embedded device, on which I use the USB gadget USB interface to either make it available as a mass storage device, or enable access over USB serial using the g_serial module.
