LIRC & FTDI: ttyUSB disappearing

[PROBLEM] Trying to set up an FTDI based (FT232RL) USB-to-UART adapter with a TSOP 4838 as infrared remote control receiver with LIRC. (Xubuntu 16.04, LIRC v0.9) The 4838 is talking to me, receiving IR signals, and LIRC's "mode2" shows reasonable output. But after I use irrecord, the seri...

Playing around with a TSOP1738 directly connected to an FTDI USB adapter (FT232RL). When I hit buttons on the remote, I see the RXD led flash, but "cat /dev/ttyUSB0" shows nothing. Thanks to a post on stackexchange , here's a command that will give you at least "something" when y...

Ubuntu & Thunderbird 60.2.1 update: Calendar gone!

[PROBLEM] On Xubuntu 16.04.1, I've updated from Thunderbird 57 (or so) to 60.2.1. In about 15 years of heavy Thunderbird usage, I've never had a problem with an update. Except for now: My calendar (Lightning) was gone/disabled - because it's incompatible with Thunderbird >60. And the addons didn't ...

TSOP1738 on Raspberry Pi: No such device

WARNING: Haven't managed to use the TSOP1738 on RPi's GPIO pins, due to noise-interference. Maybe some resistor/capacitor as filter might help. This thread might contain hints in the right direction: "IR Receiver - gives out data only while disconnecting/connecting it to ground" ? [PROBLEM...

Seems doable, but will have some reading about custom NVRAM: Some Bluetooth controller (for example, BCM4354 and BCM4356) are integrated to WiFi chipset (this can be BCM43XX 802.11ac Wireless Network Adapter or just simple generic Broadcom PCIE Wireless). These devices requires two kinds of firmware...
