I2C_HID 觸摸板晶片數據讀取
Recetly 我試圖通過韌體更新來修復我的觸摸板滯後,但它粉碎了我的整個觸摸板。現在移動是倒置的,右鍵點擊不起作用。
我的觸摸板是 ELAN1200 04F3:304E,是有史以來支持最差的觸摸板之一。
不過,我還是抱有希望的。
我知道觸摸板被辨識為 I2C-HID 設備,如果我可以用程序升級它的韌體,就可以讀取數據並將數據寫入觸摸板的晶片。
所以我正在嘗試查找已連接的 i2c 設備,但 i2cdetect -l 沒有運氣。我的 lsusb 也不顯示觸摸板:
$ lsusb Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 005: ID 0b05:1869 ASUSTek Computer, Inc. Bus 001 Device 004: ID 13d3:5666 IMC Networks Bus 001 Device 003: ID 8087:0a2b Intel Corp. Bus 001 Device 002: ID 09da:7dc8 A4Tech Co., Ltd.

雖然 xinput 辨識它:

我用來升級觸摸板韌體的程序在這裡https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1653456/comments/161
我有興趣從工作的觸摸板晶片複製數據並將其粘貼到我的。我該怎麼做?
對於所有尋求答案的人,我聯繫了 ELANTech,他們為我提供了韌體。如果有人需要它,請隨時給我寫信 vlad.dalechin@gmail.com
