Raspbian wifi driver for 0bda:f179 - driver

I recently brought my raspberry pi 3 model B+ and my wifi adapter which is a Realtek RTL8188
It doesn't work when I plug into the Raspberry pi, but works instantly on my Windows 10 Laptop

After trying to make it work for 3 hours on my Raspberry Pi 2, I found the correct driver:
0bda:f179 uses Realtek 8188FU -> look for this particular driver for your version of Raspbian. Generic versions and 8188EU will not work.
There is a script by MrEngman in https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=62371 that detects the correct version and downloads it automatically.

I can't find a NVMe driver for my new M2 Samsung 980 PRO (W10 pro 22H2)

I am using a new M2 Samsung 980 PRO. Samsung Magician says there is a unknown NVMe driver installed. I tried to do a backup based on DISM with Heise C'T wimage. Some files are corrupt, thats why backup fails. I simply would like to install a suitable NVMe driver to get rid of corrupt files on the M2 drive. Any suggestions?
I tried to do the backup four times. Each backup failed between 11 and 16%. I did already "sfc /scannow" and "chkdsk /f /r". No errors found. But when I start again the backup, corrupt files stop the backup process...

`RuntimeError: Failed to allocate tensors` When using retrained object detection model on Google Coral

I am trying to deploy an object detection model on Google Coral. I trained the model using the following config file, which I tried to closely match to the demo config file from the docker image described here.
I successfully trained my model, then I ran the script ./convert_checkpoint_to_edgetpu_tflite.sh seemingly successfully with the following output:

What am I doing wrong?
Thanks!
PS: I realize this may be more suited for a git issue, but I am not sure where to post google-coral issues on git...
I had the exact same problem with the Coral board as well after following the tutorial to retrain an object detection model.
For me the issue was due to the compiler targeting a different runtime version than I had on the Coral board. On the Coral board, you can check the runtime version like this:
python3 -c "import edgetpu.basic.edgetpu_utils; print(edgetpu.basic.edgetpu_utils.GetRuntimeVersion())"
On my board the runtime version was 10 which is not the same as the default for the compiler which was 12. If you indeed have the same issue then you can compile the model targeting this version using:
edgetpu_compiler --min_runtime_version 10 your_model.tflite
Source:
https://coral.withgoogle.com/docs/edgetpu/compiler/#compiler-and-runtime-versions
Could you try with the newest compiler and check back? I know there were a few bugs in the compiler it self which is fixed. Guide is here:

Windows Driver : Install legacy hardware with command line tool

Operation System: Windows Server 2016 R2
I have a RAMDisk driver can be installed with "Add Legacy Hardware Wizard" (hdwwiz.exe) successfully. From the output of devcon hwids *, the device can be seen as below.
ROOT\UNKNOWN\0000
Name: RAMDrive [ QSoft ] Enterprise (x64)
Hardware IDs:
ramdriv
However, I need complete the installation via Ansible, hence hdwwiz.exe cannot be used. It has to be done via command line without interaction.
I tried several approaches and none of them works.
Approach I : DevCon.exe (Windows Device Console)
C:\Ramdisk64_inst>devcon.exe install RAMDriv.inf ramdriv
Device node created. Install is complete when drivers are installed...
Updating drivers for ramdriv from C:\Ramdisk64_inst\RAMDriv.inf.
devcon.exe failed.
C:\Ramdisk64_inst>devcon.exe install RAMDriv.inf ROOT\UNKNOWN\0000
Device node created. Install is complete when drivers are installed...
Updating drivers for ROOT\UNKNOWN\0000 from C:\Ramdisk64_inst\RAMDriv.inf.
devcon.exe failed.

Approach 3 : rundll32 calls SetupAPI
C:\Ramdisk64_inst>rundll32.exe setupapi.dll,InstallHinfSection DiskInstall 128 C:\Ramdisk64_inst\RAMDriv.inf
It ends without any error, but the driver is not installed.
Approach 4 : PnPUtil
C:\Ramdisk64_inst>pnputil.exe /add-driver C:\Ramdisk64_inst\RAMDriv.inf /install /subdirs /restart
Microsoft PnP Utility
Adding driver package: RAMDriv.inf
Driver package added successfully.
Published Name: oem7.inf
Driver package installed on matching devices.
Total driver packages: 1
Added driver packages: 1
It succeeded, but in fact driver is not installed.
None of them works. DpInst.exe says No matching devices found in INF, DevCon.exe says Unable to find any matching devices. It seems the same reason.
However the driver can be installed with hdwwiz.exe manually, does anyone know what is the secret inside hdwwiz.exe?
Legacy Drivers can´t be installed with pnputil and have to use LaunchINFSectionEx-Call
I tested the following and it works with several drivers from Windows 2000 up to Windows 10, 2012R2, 2016, 2019.
rundll32.exe advpack.dll,LaunchINFSectionEx ykmd.inf,Yubico64_Install.NT,,4,N
Pay attention to use the correct section
The correct section of the inf-File must be used, when there is no [DefaultInstall]-Section. This lacks in most answers. Look it up in your drivers inf-File and use the correct section (in my example "Yubico64_Install.NT"). Using the wrong section wont prompt an error. Im my example I use Quiet mode, no UI (4) and Never reboot (N) to install the driver automated via GPO. All options are documented in detail here:

Unable to install SGX driver to intel i3 6100 CentOS 7 machine

I am trying to install the Intel SGX driver at Intel I3 6100 based CPU and I am not able to launch the enclave.
I am suspecting that it is happening due to my processor (i.e. Intel core i3). Same steps I perform at my another machine that came with I7 and it is working as expected.
Thing I tried at my end is :
First I tried to install the driver 1.7 and getting the device error.

How to use Orbbec Astra sensor/camera on ROS to view pointcloud?

I have installed ROS indigo, openni2, and plugged Orbbec Astra sensor in.
When I try to execute:

I get the warning that no device is connected:
No matching device found.... waiting for devices.
Reason: std::string openni2_wrapper::OpenNI2Driver::resolveDeviceURI(const string&)
# /tmp/buildd/ros-indigo-openni2-camera-0.2.3-0trusty-20150327-
0611/src/openni2_driver.cpp # 623 :
Invalid device number 1, there are 0 devices connected.
