我有一台裝有 PopOs 19.10 的 HP Envy 13-ad001la。讀卡機不工作;當我使用時,lspci我得到這是一個 Alcor Micro 設備讀取器:

01:00.0 Unassigned class [ff00]: Alcor Micro Device 6625
    Subsystem: Hewlett-Packard Company Device 834a
    Flags: fast devsel, IRQ 255
    Memory at a1200000 (64-bit, non-prefetchable) [disabled] [size=4K]
    Capabilities: [40] Power Management version 3
    Capabilities: [50] MSI: Enable- Count=1/1 Maskable- 64bit+
    Capabilities: [80] Express Endpoint, MSI 00
    Capabilities: [100] Latency Tolerance Reporting

據我了解,「未分配的類別」意味著Linux無法找到該裝置的驅動程式。我搜尋了對應的驅動,發現驅動是“alcor_pci”(https://cateee.net/lkddb/web-lkddb/MISC_ALCOR_PCI.html)並且它沒有加載,所以我使用 modprobe 來加載它。

 ~  lsmod | grep alcor     
alcor_pci              20480  0

但在此之後它仍然無法正常工作,lshw顯示以下內容(NO RECLAMADO 意味著未聲明):

                recursos: memoria:a1200000-a1200fff

有人可以幫我嗎?我不知道加載模組後是否需要執行其他操作。

答案1

它無法運作,因為 AU6625 裝置 ID 僅新增在linux 5.6

一些司機即使不匹配,也確實支援“強制使用”模組,但我真的不會屏住呼吸讓讀卡機支援這一點)

答案2

(本文是從法文到英文的自動翻譯。)

你好,
我用這張卡的經驗:

*"Alcor Micro AU6625 PCI-E Flash card reader controller"*

如果您願意重新編譯您的 Linux 內核,該卡似乎可以與內核中已包含的 AU6621 驅動程式配合得很好(從內核版本 5.5.6 開始)。只需在模組的源代碼中“重命名”它,然後重新編譯linux內核即可。從核心版本 5.5.9 開始,這對我有用。我已經使用它幾個月了,沒有(明顯的)問題,這些核心版本(5.5.9、5.5.16、5.6.7、5.6.9)

我的環境:

"HP ENVY Laptop 13-ad1xx"
LSPCI
02:00.0 Unassigned class [ff00]: Alcor Micro AU6625 PCI-E Flash card reader controller
Debian
Stock linux kernel: https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.6.7.tar.xz

警告,我不是開發人員,我只是一個喜歡時不時重新編譯 Linux 核心的系統管理員。

本文的其餘部分假設您已經知道如何重新編譯 Linux 核心。否則最好不要繼續這個過程;錯誤地建立核心並運行它可能非常危險,您可能會損壞硬碟上的所有資料。

提取原始程式碼後,需要在解壓縮的核心原始碼的根目錄中調整下列檔案(透過 shell 指令「$ grep -i -n -r "AU662" *" 找到)。

將所有帶有“6621”的引用更改為“6625”。

更改前: $ grep -i -r -n "AU662" *

兩個重要注意事項:

  • 從內核 5.6.x 開始,內核中似乎包含了 AU6625 驅動程式的啟動,但是這個包含的驅動程式似乎還不能工作(至少在我的配置上,直到我目前使用的 5.6.9 核心) )因此,您必須“註釋”或從程式碼中刪除這個新部分。

  • 在這個新編譯的核心上重新啟動後,“lspci”命令將繼續顯示“未分配的類別...”。
    為我

    02:00.0 未分配類別 [ff00]:Alcor Micro AU6625 PCI-E 快閃卡讀卡機控制器

但無論如何,該卡工作得很好,並且像其他卡一樣安裝在我的檔案管理器(Nautilus)中。
