Hello, Hans. You wrote 17 =D1=81=D0=B5=D0=BD=D1=82=D1=8F=D0=B1=D1=80=D1=8F 2013 =D0=B3.,= 9:14:17: HPS> Check using usbdump -i usbusX -f Y -s 65536 -vvv HPS> what is going on. Maybe some USB transfers are returning zero length d= ata from the chip. Ok, I got 500 irq/s here from my device, so, I have same problem, as topicstarter. My usbdump (9-STABLE) doesn't understand '-f Y', without filter I get: 12:42:58.929604 usbus3.2 SUBM-INTR-EP=3D00000089,SPD=3DHIGH,NFR=3D1,SLEN=3D= 0,IVAL=3D2 frame[0] READ 16 bytes flags 0xa <SHORT_XFER_OK|PIPE_BOF|0> status 0xeb023 <OPEN|TRANSFERRING|STARTED|SHORT_XFER_OK|BDMA_ENABLE|BDMA_S= ETUP|CURR_DMA_SET|CAN_CANCEL_IMMED|DOING_CALLBACK|0> 12:42:58.931601 usbus3.2 DONE-INTR-EP=3D00000089,SPD=3DHIGH,NFR=3D1,SLEN=3D= 8,IVAL=3D2,ERR=3D0 frame[0] READ 5 bytes 0000 C1 01 01 01 55 -- -- -- -- -- -- -- -- -- -- -- |....U | flags 0xa <SHORT_XFER_OK|PIPE_BOF|0> status 0xcb021 <OPEN|STARTED|SHORT_XFER_OK|BDMA_ENABLE|BDMA_SETUP|CAN_CANC= EL_IMMED|DOING_CALLBACK|0> 12:42:58.931607 usbus3.2 SUBM-INTR-EP=3D00000089,SPD=3DHIGH,NFR=3D1,SLEN=3D= 0,IVAL=3D2 frame[0] READ 16 bytes flags 0xa <SHORT_XFER_OK|PIPE_BOF|0> status 0xcb023 <OPEN|TRANSFERRING|STARTED|SHORT_XFER_OK|BDMA_ENABLE|BDMA_S= ETUP|CAN_CANCEL_IMMED|DOING_CALLBACK|0> 12:42:58.933601 usbus3.2 DONE-INTR-EP=3D00000089,SPD=3DHIGH,NFR=3D1,SLEN=3D= 8,IVAL=3D2,ERR=3D0 frame[0] READ 5 bytes 0000 C1 01 01 01 55 -- -- -- -- -- -- -- -- -- -- -- |....U | flags 0xa <SHORT_XFER_OK|PIPE_BOF|0> status 0xeb021 <OPEN|STARTED|SHORT_XFER_OK|BDMA_ENABLE|BDMA_SETUP|CURR_DMA= _SET|CAN_CANCEL_IMMED|DOING_CALLBACK|0> 12:42:58.933610 usbus3.2 SUBM-INTR-EP=3D00000089,SPD=3DHIGH,NFR=3D1,SLEN=3D= 0,IVAL=3D2 frame[0] READ 16 bytes flags 0xa <SHORT_XFER_OK|PIPE_BOF|0> status 0xeb023 <OPEN|TRANSFERRING|STARTED|SHORT_XFER_OK|BDMA_ENABLE|BDMA_S= ETUP|CURR_DMA_SET|CAN_CANCEL_IMMED|DOING_CALLBACK|0> --=20 // Black Lion AKA Lev Serebryakov <lev@FreeBSD.org>
