我使用tusb9261芯片设计了一款硬盘盒，但是传输速度只有190MB/s左右，无法远低于手册给出的最大传输速度，使用的硬盘是Gen3的硬盘，串口打印的log如下所示：

您好，
TUSB9261支持SATA Gen 1/2，数据手册没有写支持Gen3，应该是不支持Gen3。

我知道tusb9261只支持Gen1/2，但是Gen2的理论速度是3Gbps，而我的速度只到190MB，只有理论速度的一半，感觉不太正常

SATA2的理论传输频宽为3GB/S，也就是大概每秒300MB左右，由于实际传输不会到理论值那么高。我再确认下这个问题。

我咨询了美国的资深工程师，给予了这样的回复：由于SATA设备发送的数据少于主机预期的数据（基于CBW），USB Bulk in endpoint似乎反复被暂停。TUSB9261似乎正确地处理了这个案件，所以这可能是您硬盘的一个限制。当观察到此调试日志时，正在测试什么操作？
[It seems that the USB Bulk in endpoint is repeatedly being stalled due to the SATA device sending less data than the what the host expects (based on the CBW). TUSB9261 seems to be handling this case correctly so this may be a limitation of your hard disk. What operation was being tested when this debug log was observed?]

这是上电后打印的log，没有进行其他操作，应该是在进行一些初始化和器件的握手工作，在此之后，可以正常传输文件，使用的硬盘在log中可以看出已经识别到了
