[Spice-devel] Usb redirection

[Jackson]

OK! I use spice-gtk with usb redirection 0.4.3 and trying to redirect webcam to 
VM. There are some problems causing the client crashed when 
usbredir_free_write_cb_data()->usbredirhost_free_write_buffer()->...try to free 
data. 
And I print the data in usbredir_write_callback() & usbredir_free_write_cb_data()
...
write_data = 100
free_data = 100
write_data = 17
write_data = 17
write_data = 4
write_data = 5
write_data = 11
free_data = 17
free_data = 238(error)

Any possible problem cause the error?
