A new Windows 8.1 namespace offers app support for USB devices: Windows.Devices.Usb. You can use it to write a Windows Store app that talks to a custom USB device. Custom in this context means a peripheral device for which Microsoft does not provide an in-box class driver.
Marijuana Effects: Sativa. Sativa strains are more of a stimulant, and are effective in appetite stimulation, relieving depression, migraines, chronic pain and nausea. Common strains include: Haze, Trainwreck, K2, Kali Mist White Russian and Kiwi Green.
indica. Indica is not slang for marijuana, but one of the three species of marijuana; Sativa, Indica, and Reduralis. Sativa is more of a skinny, tall, lanky, and less yielding plant that produces a mind high. Whereas Indica is more of a small, broad, and usually a higher yielding plant that gives you a couchlock body high. Rederalis isn't grown due to its small amount of THC but is sometimes crossed with other species to shorten flowering time.
