請問如何列出無法辨識的裝置？

3ldk

想在xfce和kde plasma加入fingerprint login

教學的第一步就係用依句先睇睇部機的fingerprint reader是否support
lsusb | grep FingerPrint

但卻沒有任何output, 咁即係未裝driver還是部機根本無依個device? 點分辨？


我估應該係未裝driver, 因為睇部機的power button係類似指紋款

既然如此，理論上係咪應該會有另一個command, 可以徹底將所有無法辨識的裝置print出來？

lsusb will list all usb devices, you can find all known devices with their names and unknown devices with their usb id. search usb id to see if there is driver available.

我的係Validity Sensors, Inc. VFS 5011 fingerprint sensor
所以要case insensitive grep :     lsusb | grep -i FingerPrint

其實無乜關係, 雖然我問題寫用左lsusb | grep FingerPrint
但實際上我只係用lsusb, 沒有grep, 所以同case無關係, output係見唔到任何fingerprint之類的字眼

當然, 亦搵唔到有unknown等字眼

can you post your output of
lsusb

here is the output

Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

did not see any fingerprint related device.
1) you sure you have one ?
2) may be it is a pci device. (check dmesg )

唔100%肯定, 因為說明書寫得比較奇怪, 第一句話 Touch style fingerprint reader integrated in power button

第二句卻係 No fingerprint reader

不過我有其他線索可以合理懷疑有fingerprint, 用model去搵driver, 會見到fingerprint driver, 而且寫明係Type 21CS的driver.

如果用dmesg | grep inger
係grep唔到任何野

但如果dmesg | grep unknown
則會grep到一個同音效有關的硬件
sof-audio-pci-intel-tgl 0000:00:1f.3: unknown sof_ext_man header type 3 size 0x30

dmesg | grep pci
就會grep到好多行, 睇過無乜值得懷疑的item

試下
lspci

lspci都係沒有

而家用唔用到指紋都唔緊要了

反而想知道Linux究竟有無一個統一的位置可以睇到所有插左落電腦的hardware? 無論果件hardware用唔用到

就好似windows, 所有用到用唔到的, 都會係裝置管理員入面見到

反而Linux要先知道件hardware用usb連接定pci連接先check到? 萬一唔係usb同pci咁點check? 有時內部既hardware係睇唔到點連接, 咁點可以判斷出, 究竟係根本無果件hardware, 還是壞左, 還是不support?
