你的这个问题我查一下，类似的情况还是有的。硬件不知是否你们自己做的呢？如果你们确定硬件没有问题，请点击以下链接更新一下PSP，一般是内核驱动的BUG：

software-dl.ti.com/.../index.html

我们不进行电话支持的，流程很麻烦。。。抱歉。

您好！

您能否提供详细点的信息，这些网页我都有看，但不能确定能否解决问题，我又不想试试的心态去解决这个问题，因为我们时间有限，谢谢！

你的信息显示“version 2.6.10_mvl401-davinci_evm (root@localhost.localdomain) (gcc versio     n 3.4.3 (MontaVista 3.4.3-25.0.30”你的Linux版本是2.6.10的，MontaVista 3.4.3的，都是很低的版本。

而'LSP 2.00' Production Release的版本是Linux Support Package (Kernel 2.6.18)，MontaVista Pro 5.0.0。

另外你的板子如果不是TI的EVM板，这个问题我不能给你保证。

1. 硬件是否是公板

2. 鼠标是USB1.1的吧，是直接接的开发板的USB Host么

3. 是每次都稳定的出Error还是随机出现

我猜应该不是公板，是DM6446的VBUS那块硬件电路和内核的驱动不匹配造成的

现在1.1的usb鼠标比较少吧？我们使用的是联想台式机的鼠标。

只能说经常出现VBUS_ERR的错误，很少能成功使用usb鼠标。

不是公板。那如何解决？能详细点吗？

LSP 1.0是2.6.10内核的。我下载了，但是里头有几个usb的补丁，我也不清楚是那个，该如何更新驱动？

我现在用nfs将板子挂载到了宿主机上。

usb 1-1: new low speed USB device using musb_hdrc and address 2

input: USB HID v1.11 Mouse [USB Optical Mouse] on usb-musb_hdrc-1

这是正常启动后的打印出来的usb部分信息，这是说我的鼠标是1.1，还是板子的usb是1.1 ？

我看usb的文档，板子上应该是2.0的usb。

如果我使用usb1.1鼠标在usb2.0上，会是产生这个问题的原因吗？ 我更换一下可行吗？

。。。。。。。。。。。。。。。。。。。

usb 1-1: new low speed USB device using musb_hdrc and address 2

这些信息说明什么？我该使用什么样的usb鼠标？
