The NAS has a Fresco Logic FL1009 > XHCI controller: I can add the following: 2) I just tested the copy of the small files using the ICY DOCK MB981U3S-1S connected to my ReadyNAS 102 *on a 3.11.7 kernel* and it completed successfully. 2) on current 3.13.0-rc7 kernel (w/ Bjørn patch applied just in case), I just transferred 40GB through a Logitec LAN-GT JU3H3 (it is based on an ASIX AX88179) connected to my ReadyNAS Duo v2 (NEC XHCI controller) at an average rate of 82MB/s. Bottom line: no issue. When I try to do the same on my ReadyNAS 102, I immediately get complaints: [ 383.280429] xhci_hcd 0000:02:00.0: ep 0x82 - asked for 20480 bytes, 20400 bytes untransferred [ 383.280892] xhci_hcd 0000:02:00.0: ep 0x82 - asked for 20480 bytes, 20400 bytes untransferred [ 411.620073] xhci_hcd 0000:02:00.0: ep 0x82 - asked for 20480 bytes, 20352 bytes untransferred [ 411.620750] xhci_hcd 0000:02:00.0: ep 0x82 - asked for 20480 bytes, 20400 bytes untransferred [ 411.621727] xhci_hcd 0000:02:00.0: ep 0x82 - asked for 20480 bytes, 20400 bytes untransferred [ 412.066651] xhci_hcd 0000:02:00.0: ep 0x82 - asked for 20480 bytes, 20352 bytes untransferred [ 412.067233] xhci_hcd 0000:02:00.0: ep 0x82 - asked for 20480 bytes, 20400 bytes untransferred [ 412.068196] xhci_hcd 0000:02:00.0: ep 0x82 - asked for 20480 bytes, 20400 bytes untransferred [ 412.242708] xhci_hcd 0000:02:00.0: ep 0x82 - asked for 20480 bytes, 20352 bytes untransferred [ 412.243333] xhci_hcd 0000:02:00.0: ep 0x82 - asked for 20480 bytes, 20400 bytes untransferred [ 412.244246] xhci_hcd 0000:02:00.0: ep 0x82 - asked for 20480 bytes, 20400 bytes untransferred [ 412.417956] xhci_hcd 0000:02:00.0: ep 0x82 - asked for 20480 bytes, 20352 bytes untransferred [ 412.418516] xhci_hcd 0000:02:00.0: ep 0x82 - asked for 20480 bytes, 20400 bytes untransferred [ 412.419473] xhci_hcd 0000:02:00.0: ep 0x82 - asked for 20480 bytes, 20400 bytes untransferred [ 412.545330] xhci_hcd 0000:02:00.0: ep 0x82 - asked for 20480 bytes, 20352 bytes untransferred If someone has a system w/ a Fresco Logic FL1009, I would be interested by some feedback on how it behaves w/ current kernel.
