'Realtek RTL2832U reference design:1-1.4' successfully deinitialized and disconnected #141

Closed kkruzich closed 2 years ago

kkruzich commented 2 years ago

I have Ubuntu Focal 20.04. Below is output from dmesg and rtl_433 Prior to running rtl_433 dmesg shows the RTL2832U initialized and connected. However once I run rtl_433 I see the successfully deinitialized and disconnected message. After several minutes I don't see any messages from the weather station.

The weather station is an Acurite Atlas. I can provide more details if necessary.

I realize this is probably more of an rtl_433 or kernel module issue but I thought I'd check in here to see if you can help spot what I'm overlooking.

See last log entry below is from different computer / weather station / same dongle.

sorry, this looks like an rtl_433 problem
