Hello, I have a Raspberry Pi 4 model B 8GB running 5.4.79-v7l+. I have bought it to replace my previous Raspberry Pi 3. The Pi 3 was connected via USB with an Oregon Scientific Weather Station (WMR89) and used CP210X driver to communicate with it. As the pair Vendor/Product ID wasn't registered in the driver CP210x.c, I added it using
echo 0fde ca0a > /sys/bus/usb-serial/drivers/cp210x/new_id in boot (rc.local). With the Raspberry Pi 3 the weather station was always automatically recognised, drivers loaded and accesible though /dev/ttyUSB and weewx run without problems. However, I am unable to get the same results with the Raspberry Pi 4. I have to unplug and plug manually every time the device to get it loaded. I have even built a new cp210x module including oregon's pair vendor/product ID to see if it helps but I am still stuck in the same point: I need to plug and unplug the USB cable from the weather station to make it work. Replugging the type A connector in the Raspberry Pi will make no difference. I have to replug the mini USB in the weather station to make it work (what seems really strange). Does anybody has an idea on how to solve this problem? Thanks! Daniel -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
