Jawaban:
Untuk beberapa alasan, perangkat ini tiba-tiba dihapus oleh kernel atau pengontrol USB dengan cara yang tidak bersih, sehingga meninggalkan
/dev
simpul - simpul tersebut.Ini adalah perangkat USB2!
Seperti yang saya lihat data spesifikasi SanDisk Cruzer Blade .:
Seharusnya perangkat USB2. Jadi bisa bermasalah dengan port USB3
Ubah ke port USB2 lain laptop Anda seharusnya sudah memiliki 2 port ( Lenovo ThinkPad T440p spec. ).
Jelas yang
xhci_hcd
terdeteksi sebagai perangkat USB2 dari deskripsinyaPerangkat USB3 harus mendapatkan
super-speed
atausuper-speed+
. Referensi: Wikipedia: USB, Riwayat VersiOpsi 1. Nonaktifkan USB3 dari BIOS
Ini menyebutkan manual :
+
tanda itu adalah USB2)BIOS memiliki opsi untuk menonaktifkan USB3 pada 2 port bersama antara USB2 & USB3. Sisi mana? Saya tidak tahu!
Jadi mungkin port bersama adalah yang ada di sisi kanan. Nonaktifkan USB3 dari BIOS dan lihat apa output baru
dmesg
di kedua sisi, ditambah output darilsusb
.Opsi 2. Tingkatkan BIOS / UEFI
Ada rilis baru:
Catatan rilis menyebutkan masalah USB terhitung, yang paling menarik adalah ini:
