我在使用非 Android/移动设备的特定设备时遇到了问题。
这是一个带有内置硬盘的媒体播放器，我正尝试将其作为大容量存储设备连接，以便可以从中复制电影/电视剧。
当我将其连接到我的系统时，我看到以下内容
kernel: usb 1-4: new high-speed USB device number 7 using xhci_hcd
systemd[1]: Starting Cleanup of Temporary Directories...

答案1
经过大量阅读和测试。
我发现这与默认 Udev 规则的最新更改有关，如果设备与任何其他 USB 设备的 udev 规则不匹配，则为由 MTP 处理的设备设置一条捕获所有规则。
而不是像以前一样将我的设备安装为 USB 大容量存储设备。
我发现我需要让 udev 知道这个设备应该由 USB 大容量存储设备管理，而不是由 MTP 捕获所有规则管理
首先我需要我的设备 ID。下面是列表中的最后一个
$ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 8087:0a2a Intel Corp.
Bus 001 Device 002: ID 04f2:b51d Chicony Electronics Co., Ltd
Bus 001 Device 006: ID 04e8:6860 Samsung Electronics Co., Ltd Galaxy (MTP)
Bus 001 Device 005: ID 0b05:181b ASUSTek Computer, Inc.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 007: ID 174c:5106 ASMedia Technology Inc
我确信这里还有更多内容，但这对我来说是可行的。我获取设备 ID174c:5106并将其替换到下面的 udev 规则中。
$ cat /etc/udev/rules.d/90-myrules.rules
SUBSYSTEMS=="usb", ENV{MODALIAS}=="usb:174c:5106", ENV{MODALIAS}="usb-storage"
您需要重新启动/重新加载 udev 来更新规则。
systemctl reload systemd-udevd.service
或者
systemctl restart systemd-udevd
我现在在系统日志中看到以下内容
journalctl -fe

答案2
首先将文件复制/lib/udev/rules.d/69-libmtp.rules到/etc/udev/rules.d/69-libmtp.rules：
$ sudo cp /lib/udev/rules.d/69-libmtp.rules /etc/udev/rules.d/69-libmtp.rules
在此文件的顶部，你可以找到：
# Some sensitive devices we surely don't wanna probe
ATTR{idVendor}=="0670", GOTO="libmtp_rules_end"
ATTR{idVendor}=="0471", ATTR{idProduct}=="083f", GOTO="libmtp_rules_end"
mtp-probe然后通过在上述行之后添加下一行来排除该设备：
ATTR{idVendor}=="093a", ATTR{idProduct}=="2516", GOTO="libmtp_rules_end"
我使用 shell 命令找到了我的 USB 设备 ID lsusb。它是093a:2516

我正在尝试使用 ThinkPad Dock 断开外围设备连接（这里) 检查 journalctl 时，我发现断开连接前的最后一行显示 mtp-probe 设备错误，我认为原因可能与此处显示的相同，但与我的显示器有关。我如何找到我的设备以将其排除在 mtp-probe 之外？
