A NAS. or SSD. But if you your ability to configure it's your own personal cloud and can hold a lot of storage. I have thought about this for years and finally bought one. It's a learning and I riding that curve hard but I think it's worth the time energy, efficiency, and if it matters to you a lot protection. I explained it to my parents as a way to backup ...

Filesystems won't effect speed any where near as much as LUKS.
zfs/btrfs/lvm+xfs/mdadm+ext4 will all hit N drive speed.
Other SOCs in the same price range have much better encryption performance:
aes-xts 512b benchmarks:
MiB/s, Product
9.7, RPI 1
18.8, HiFive Unmatched (U740)
22.5, RPI 3

60.0, USB2 ===

The problem is Windows 10 unable to detect the USB Ethernet gadget.
You need to install the drivers through a windows update or by a google search.

I got your code working with my USB GPS using the following:
dmesg shows my USB GPS connected on ttyACM0:
[557325.587821] usb 1-1.3: New USB device found, idVendor=1546, idProduct=01a8, bcdDevice= 3.01
[557325.587827] usb 1-1.3: New USB device strings: Mfr=1, Product=2, SerialNumber=0

x-systemd.device-timeout=100ms is ridiculously small for a mechanical drive, which can easily take 5-10 seconds to spin-up. The fact that it worked in Stretch is just a coincidence. Since the partition data which defines the existence of e.g. /dev/sda1 resides on the drive, such device files will not be created until the disk is fully operational.
I ...

Good news, the Raspbian has CDC ACM drivers already built in as plug-and-play, so /dev/ttyACM0 should show up when you plug your adapter in if it actually CDC ACM.
"/dev/ttyACM0" is USB0, On my system they generally show up as "/dev/ttyUSBx" I have seen on some of my Linux machines but not recently. That also varies with the IDE I am ...

After much additional struggling in vain, I abandoned my quest to make my original pi work. I simply took a new SD card and rebuilt the system from scratch using the current Raspberry Pi OS Buster image. With that image, I just plugged the printer/scanner into the USB port and both printing and scanning to the HP PSC 750xi worked 'right out of the box' ...

I have similar errors. I can boot but with longer/larger read/writes it kicks my hard drives out again and again. I have unfortunately not found a solution yet.
sudo dmesg should give you more information. Do you find something like:
[ 26.655337] usb 2-1.3: reset SuperSpeed Gen 1 USB device number 4 using xhci_hcd
[ 26.675456] usb 2-1.3: device firmware ...

Others have already answered most of this, but I think this page on testing USB cables from someone who actually carried out detailed measurements of cable performance contains more insight. Quoting: "It's essentially impossible to reliably power a Pi off a cable over 1m long using a USB cable. You simply cannot run 5V through that length of thin wire ...

I can confirm the sensor is now setup correctly.
Steps:
Update sources
$ sudo apt-get update
Install the gps daemon, libraries and NTP
$ sudo apt-get install gpsd gpsd-clients ntp
Modify /dev/ttyACM0 file (NTP won't work without the -n)
$ sudo cat /dev/ttyACM0
#add followings
DEVICES="/dev/ttyACM0"
GPSD_OPTIONS="-n"
Edit the ntp ...

Looks like a baudrate change, or a switchover to a binary protocol. Connect to the GPS using U-center and check how it is configured.

Ensure that your user belongs to audio group.
To check groups of the currently logged user:
groups "${USER}"
To add yourself to the audio group:
sudo usermod -aG audio "${USER}"
That probably needs relogging for the changes to take effect.
You can try once again list your sound-cards:
aplay -l
To test you have the access to a sound-...

Your logs show that your system repeatedly gets under-voltage warnings. Find a better power supply and cable, and verify that you don't get such warnings.
If the under-voltage warnings are gone and the SSD is still not working properly, the next thing to try is to switch from UAS driver to mass storage driver using usb-storage.quirks=<VID>:<PID>:...

You can do it via USB HID, re. the Pico works as a Keyboard, sending data to a connected computer.

As a reminder in case someone else stumble on this thread in the future, I got the max3421 working for an RPi 0 W 1.1 on kernel 5.10.63+ while building the kernel module 'out of tree' & only DL-ing the necessary headers.
Since a .dts overlay is the only thing missing in the RPi firmware repo on github ( as of today at least ), I'll be pushing my tweak as ...

1&2 :In general, it is better to keep your own rules separate from the system rules. I would create a file /etc/udev/rules.d/50-localusb.rules with the content:
SUBSYSTEMS=="usb", ATTRS{idVendor}=="067b", ATTRS{idProduct}=="2303", GROUP="dialin", MODE="0666"
You may get idVendor and idProduct from an ...

It is a hardware problem, somehow.
Some background: The message is probably generated by drivers/usb/hub.c; the comment section above it says:
/*
* EM interference sometimes causes bad shielded USB devices to
* be shutdown by the hub, this hack enables them again.
* Works at least with mouse driver.
*/
The real reason needs some investigation. Your UMTS ...

requires an active internet connection on the pi and my phone connected to the same network
MiniDNLA does not require the former if by "internet connection" you mean something with access to the WWW ("internet" can be taken more broadly to refer to any IP based network, which would include two computers with an ethernet cable etc). But ...

I have just heard back from the YunoHost dev team...
"My very, very, bad. I mistyped or somehow forgot you were on Raspberry. You need Raspbian 10/Buster image, not pure Debian, to be sure all the appropriate software are installed."
So, back I go to installing YunoHost v4.1.7.2, which is bundled with Raspbian already, then I can do the upgrade ...

This is likely an issue of missing RNDIS drivers.
I worked through the same issue today, I was seeing it with both the latest Bullseye (2021-10-30) and and the current legacy Buster (2021-12-02) image of Raspberry Pi OS.
This thread helped me out, after installing the USB Ethernet/RNDIS Gadget from the optional drivers in Windows Update my Raspberry Pi was ...

You don't need to use wvdial.
Most USB 4G dongles contain multiple logical devices. You need usb_modeswitch to make Linux recognize the modem and NetworkManager to manage the connection.
The guide is here: https://whiteboxcellphone.com/psd/usb4g-linux.html

Start by finding out what driver your device gets (look into dmesg logs for a start). Those dongles often present themselves as flash disks containing windows drivers, and special trickery is required to get them recognized as modem devices.
If your dongle is recognized as a modem, look for a wvdial configuration for your specific model and see if sudo ...

Please note the port designations ETH0 and ETH1 should be reversed in step 5 above. You want internal to external packets accepted by default, not vice versa.
