ASUS U3100 Mini Plus 安装失败

华硕 U3100 Mini Plus 有点问题（https://www.linuxtv.org/wiki/index.php/Asus_U3100_Mini_plus_DVB-T) 在 Mint Serena 之下……

以下是详细信息。Mint 版本：

# cat /etc/issue
Linux Mint 18.1 Serena \n \l

#

设备：

# lsusb |grep 1779
Bus 003 Device 006: ID 0b05:1779 ASUSTek Computer, Inc. My Cinema U3100 Mini Plus [AF9035A]
#

所以我安装了固件（https://raw.githubusercontent.com/OpenELEC/dvb-firmware/master/firmware/dvb-usb-af9035-02.fw)，按照 USBHID 的要求做了怪癖的事情（实际上需要将怪癖添加为启动选项，因为将选项添加到 /etc/modprobe.d/usbhid.conf 不起作用......）：

# grep usbhid /boot/grub/grub.cfg
            linux   /boot/vmlinuz-4.4.0-104-generic root=UUID=400236d1-d186-4a9c-87db-cc987268f0ce ro  quiet splash $vt_handoff usbhid.quirks=0x0b05:0x1779:0x0004
#

以下是 dmesg 的输出：

Udev 对此做了一些事情，但我不确定这里发生了什么：

# udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

并且，模块似乎已经加载：

# lsmod| egrep 'dvb|af'
af9033                 40960  0
dvb_usb_af9035         36864  0
dvb_usb_v2             36864  1 dvb_usb_af9035
dvb_core              122880  1 dvb_usb_v2
rc_core                28672  2 dvb_usb_v2,dvb_usb_af9035
#

我看到的问题是（来自 lshw 的输出）该设备似乎无人认领并且系统认为它是键盘：

          *-usb:0 UNCLAIMED
               description: Keyboard
               product: AF9035A USB Device
               vendor: Afa Technologies Inc.
               physical id: 1
               bus info: usb@3:1
               version: 2.00
               serial: CT<snip>
               capabilities: usb-2.00
               configuration: maxpower=500mA speed=480Mbit/s

/dev/dvb/ 下没有条目

# ls /dev/dvb*
ls: cannot access '/dev/dvb*': No such file or directory
#

设备在 Windows 中运行。

有任何想法吗？

答案1

您必须在文件 (/etc/udev/rules.d/filenameofyourchoice.rules) 中为 udev 编写一条 udev 规则，以避免将该棒识别为 HID 设备。我目前正在尝试，但尚未找到正确的语法。有人说应该是这样的：

ACTION=="添加", ATTR{idVendor}=="0b05", ATTR{idProduct}=="1779", RUN="/bin/sh -c 'echo 0 >/sys/\$devpath/authorized'"

祝你好运，把你的经验回馈给我们……

答案2

因此，分享...

@user879862 您所指出的并不是我所需要的，但它确实为我指明了正确的方向，所以谢谢你！顺便说一句，直到几天前我安装 Xubuntu 18.04 而不是 Mint 时，我才看到您的回答... 现在一切正常，这可能也适用于 Mint。

需要添加一条规则来解除 usbhid 的绑定：

ACTION=="add", ATTR{idVendor}=="0b05", ATTR{idProduct}=="1779", RUN="/bin/sh -c 'echo -n $kernel >/sys/bus/usb/drivers/usbhid/unbind'"

然后，我从这里下载了FWhttp://palosaari.fi/linux/：

# cksum /lib/firmware/dvb-usb-af9035-02.fw
1601101614 41872 /lib/firmware/dvb-usb-af9035-02.fw
#

就是这样。非常简单，但弄清楚这一点很痛苦，因为我不知道这是如何工作的......无论如何，这对我很有帮助，希望它也能帮助别人：
