what usb wifi dongle do you guys use?
any that is compatible out of the box with RPi 2 & Raspbian Wheezy? do i must use the one built specifically for RPi because i read somewhere that the USB ports doesn't provide enough power for common dongle. anyone can clarify this? |

QUOTE(Ubitap @ Jan 19 2016, 04:40 PM) Yes, just get that line in the config.txt file. Thanks for your help, will try it later.Uncomment it if it's commented or write a new line if it's not there. BTW, do you sell R-Pi Zero? |

hi guys..
i just bought this HDD enclosure (link) & hook it up to my RPi3 via USB cable.. problem is when transferring files between HDD inside the enclosure (eg: from HDD in bay1 to HDD in bay2), the speed is really slow (~ 10MB/s). is the RPi3 the bottleneck here?

QUOTE(kingkingyyk @ May 11 2017, 04:32 PM) Yes. https://www.raspberrypi.org/documentation/h...i/usb/README.md the enclosure has its own power supply, not drawing power from the RPi USB portThat is normal to have that. The USB ports are seperated from internal USB hub (Microchip USB+Ethernet chip), so all of them are shared on 480Mbps bus. It also could due to insufficient power output from the Pi. The proper way is to have a powered USB hub connect to both Pi and external HDD.  |

QUOTE(kingkingyyk @ May 12 2017, 07:28 AM) Great, was wondering how the HDD is powered up with the small current from Pi. so what do you think causing the slow speed? RPi is only supposed to be telling HDDs to transfer file to each other, the data doesnt actually goes into RPi right? |
