N800 (and N810 too) does host mode and does supply at least 100mA, possibly a bit more (200mA). dmesg output from N800 with 2008 firmware has following lines [ 18.726562] musb_hdrc musb_hdrc: MUSB HDRC host driver [ 18.726562] drivers/usb/core/inode.c: creating file 'devices' [ 18.726562] drivers/usb/core/inode.c: creating file '001' [ 18.726562] musb_hdrc musb_hdrc: new USB bus registered, assigned bus number 1 [ 18.726562] musb_hdrc musb_hdrc: supports USB remote wakeup [ 18.726562] usb usb1: default language 0x0409 [ 18.726562] usb usb1: new device strings: Mfr=3, Product=2, SerialNumber=1 [ 18.726562] usb usb1: Product: MUSB HDRC host driver [ 18.726562] usb usb1: Manufacturer: Linux 2.6.21-omap1 musb-hcd [ 18.726562] usb usb1: SerialNumber: musb_hdrc [ 18.726562] usb usb1: uevent [ 18.726562] usb usb1: usb_probe_device [ 18.726562] usb usb1: configuration #1 chosen from 1 choice [ 18.726562] usb usb1: adding 1-0:1.0 (config #1, interface 0) [ 18.726562] usb 1-0:1.0: uevent [ 18.726562] hub 1-0:1.0: usb_probe_interface [ 18.726562] hub 1-0:1.0: usb_probe_interface - got id [ 18.726562] hub 1-0:1.0: USB hub found [ 18.726562] hub 1-0:1.0: 1 port detected [ 18.726562] hub 1-0:1.0: standalone hub [ 18.726562] hub 1-0:1.0: individual port power switching [ 18.726562] hub 1-0:1.0: no over-current protection [ 18.726562] hub 1-0:1.0: Single TT [ 18.726562] hub 1-0:1.0: TT requires at most 8 FS bit times (666 ns) [ 18.726562] hub 1-0:1.0: power on to power good time: 10ms [ 18.726562] hub 1-0:1.0: 200mA bus power budget for each child [ 18.726562] hub 1-0:1.0: local power source is good [ 18.726562] hub 1-0:1.0: enabling power on all ports same output is also on N810.
