Заказал 3 месяца (3, сука, месяца назад, при этом 90% времени посылка пролежала где-то в Казахстане) [url=https://aliexpress.com/item/4000288559314.html][/url] вот такой вот свисток с цветом "Цвет: V5.0 NO drive". Подключил к компу, кеды его не видят. dmesg говорит следующее:

@ RAW Close: hciconfig

Гуглёж говорит, что надо удалить несколько строк из модуля ядра. На данный момент качаю исходники ядра, но вдруг есть более или менее нормальное решение?

UPD: ядро сменил на другое:

Код:
user@linux ~> uname -a

Linux linux 5.7.0-18.1-liquorix-amd64 #1 ZEN SMP PREEMPT liquorix 5.7-23ubuntu1~focal (2020-08-26) x86_64 x86_64 x86_64 GNU/Linux

Для новых версий ядра патч пока не нашёл. Скрипт отсюда пытается качать исходники от 5.7.0, а их на сервере нет, и вообще пытается что-то копировать из несуществующего места:

Код:
cp /usr/lib/modules/$fullversion/build/.config $name/

cp /usr/lib/modules/$fullversion/build/Module.symvers $name/

Но если подменить версию скачиваемых исходников на 5.7.1, и пути к модулям, то выйдет это:

Код:
