硬件支持的条件下肯定是越大越好
[297130.539201] usb 1-1: config 1 interface 1 altsetting 0 bulk endpoint 0x4 has invalid maxpacket 64 If the information at the following link sourceforge.net/p/libusb/mailman/message/32662224/ is correct, it would appear the JLink is reporting the...
The camera uses a Max Packet Size (MPS) of 524 bytes instead of the maximum 512 bytes, leaving us 12 bytes short in the buffer. This seems to consist of a 12-byte UVC header plus [256 pixels per line * 2 bytes per pixel]. Is the 512-byte limit a hard physical constraint, with ...
…peed device A virtual SuperSpeed device in the FreeBSD BVCP package (https://bhyve.npulse.net/) presents an invalid ep0 maxpacket size of 256. It stopped working with Linux following a recent commit because now we check these sizes more carefully than before. Fix this regression by using...
