IRToy not receiving on linux May 04, 2020, 05:39:17 am I purchased an IRToy v2 from SeeedStudio, and haven't been able to receive signals yet.I am connecting the IRToy to an Ubuntu 18.04.4 LTS machine with lirc 0.10.0.I first tried following USB IR Toy: Configure LIRC. irrecord only got to Hold down an arbitrary button with the incantation sudo irrecord -H irman -d /dev/ttyACM1 remote.conf. It always gave Timeout (10 sec), giving up..I searched for relevant info. I found this forum and mythtv's IRToy page. Both pushed me to upgrade the firmware. I had trouble telling when the device was in firmware upgrade mode. I used screen to send "$" to the device. Usually, the orange LED would come on. Sometimes, the orange LED would turn on just from physically moving the device. I tried with fw_update from jesshaas.com and dpavlin/fw_update.git. With sudo ./fw_update -e -w -v -m all -vid 0x04D8 -pid 0xFD08 -ix ../USBIRToyv24.hex I got error U2IO flash erasing: FAILED. Segmentation fault. That was a couple days ago.Today, I tried things again. irrecord couldn't see any events on the first run. If I run irrecord a second time, I get "Could not init hardware (lircd running ? --> close it, check permissions)". Only unplugging and replugging allowed irrecord to get to "Hold down an arbitrary button" again. I saw that the device should respond to "t" and "v" commands. "v" outputs "V212". "t" freezes the device (and screen) to the point that only unplugging and replugging works.I gave the firmware command again "$". screen immediately disconnected. Now the device is behaving differently. The orange LED is always on. The device does not show up on /dev/ttyACM1 anymore. The dmesg output is different (see below). The fw_update command now shows "U2IO flash erasing: FAILED. Device is not found. Operation aborted."How can I receive IR remote signals with my IR Toy on my ubuntu computer?dmesg before today:Code: [Select]usb 3-4: new full-speed USB device number 28 using xhci_hcdusb 3-4: New USB device found, idVendor=04d8, idProduct=fd08usb 3-4: New USB device strings: Mfr=1, Product=2, SerialNumber=0usb 3-4: Product: USBIRtoy (CDC-232)usb 3-4: Manufacturer: DangerousPrototypes.comcdc_acm 3-4:1.0: ttyACM1: USB ACM devicedmesg after "$" command today:Code: [Select]usb 3-4: new full-speed USB device number 30 using xhci_hcdusb 3-4: string descriptor 0 read error: -71usb 3-4: New USB device found, idVendor=04d8, idProduct=fd0busb 3-4: New USB device strings: Mfr=1, Product=2, SerialNumber=0hid-generic 0003:04D8:FD0B.0009: hidraw0: USB HID v1.01 Device [HID 04d8:fd0b] on usb-0000:00:14.0-4/input0I have tried with remotes for a Roomba, Vizio sound bar, and Benq projector.
